Cochrane launches new feature to identify retracted publications

4 months 1 week ago

New Cochrane Library feature will help Information Specialists and systematic review authors produce trustworthy evidence.

Cochrane has launched a new feature in CENTRAL, our database of reports of clinical trials, to identify and flag publications that have been retracted by the publisher.

Cochrane's policy for managing potentially problematic studies states that studies with associated retractions should not be included in Cochrane reviews. This has previously been harder to achieve than it should be due to inconsistent ways of tagging published retractions that affects their accessibility and discoverability. But recent developments to standardise retractions and open the curated Retraction Watch database are helping address this.

To help Information Specialists and systematic review authors produce timely and trustworthy evidence that does not include problematic studies, we have been working hard to identify when a report of a randomized controlled trial is retracted; and to consistently label these as retracted publications in CENTRAL, with publication type label Retracted publication:pt. You can read our FAQ page on retracted publications to find out more about what sources we are using to identify these, and our plans to use additional sources in the future to identify more.

New for January 2025

This month we launch the first feature that helps users of CENTRAL (Cochrane’s database of trials) on the Cochrane Library better identify retracted publications in CENTRAL. When a user of Search Manager conducts a search, and views results in the Trials tab, if their search results contain records to papers retracted by the publisher a banner will appear, alerting them:

This will mean that when conducting a search for a review, it will be easier to identify known retracted publications. Why do we say ‘known’ retracted publications? In practice, “Although a journal may retract a publication, the communication of that retraction is often incomplete, both in the use of vague retraction notices with euphemistic language and the inconsistent and ineffective annotation of retracted publications.” (Bakker 2024). 

Plans for 2025

This work doesn’t end here, we need to do more to ensure that studies with associated retractions are not included in Cochrane reviews. There are additional challenges because, 'identifying retracted publications is important but logistically challenging; publications may be retracted while a review is in preparation or in press and problems with a publication may also be discovered after the evidence synthesis is published' (Bakker 2024).

We are currently linking those studies we have identified with retracted publications to published and in progress Cochrane reviews. Developments will also include automatic ways to inform the authors of these Cochrane reviews about the retractions, in order to proactively address this challenge; and to ensure that Cochrane remains the home of trustworthy evidence.

Hints and tips

CENTRAL is a unique source for identifying reports of randomized controlled trials retracted by publishers. Want to make the most of this valuable data source, and the new feature on the Cochrane Library? There is further information available on the Cochrane Library, and in this short video below which offers practical tips for users of CENTRAL via Search Manager on the Cochrane Library.

Showcase your peer review contributions on Web of Science

4 months 1 week ago

Cochrane peer reviewers can now feature their peer review activity on their Web of Science profiles thanks to a new collaboration between Cochrane and Clarivate. 

Clarivate operates the Web of Science platform, a database that tracks citations, authorship and contributions in peer-reviewed scientific journals. The Web of Science Reviewer Recognition Service allows peer reviewers to track, verify and showcase their work and expertise through the platform.  

“We are extremely grateful to all our peer reviewers, Associate Editors, and Senior Editors who again and again volunteer their expertise and time to actively support Cochrane,” says Colleen Ovelman, Head of Editorial at Cochrane. “As a small token of gratitude, we have ensured that their hard work is now automatically recognized on their Web of Science reviewer profile.” 

All peer reviewers contributing to Cochrane reviews from 15 January 2025 onwards have the option to showcase their contributions on Web of Science. Unfortunately we are not able to recognise historical contributions in this way.  

What do peer reviewers need to do?  

If you already have a Web of Science profile, you do not need to create a new one to benefit from this service. If you do not yet have a Web of Science profile, you can sign up now for free.  

To ensure your contributions appear on your Web of Science profile: when you next provide feedback on a Cochrane review using an online peer review form in Editorial Manager, please answer 'Yes' to the question "Would you like to receive recognition for this contribution on Web of Science?". A record of your contribution will then be sent automatically from Editorial Manager to your Web of Science profile. The contribution should appear on your profile within 48 hours.  

Don’t forget: your contributions as a peer reviewer also go towards earning you Cochrane Membership. You can track your contributions as a peer reviewer in your Cochrane Account. 

You can get involved in peer review via Cochrane Engage by searching for tasks tagged as methodological, clinical or consumer depending on your role.

Antidepressants reduce anxiety, but long-term impact remains unclear

4 months 1 week ago

A new Cochrane review confirms that antidepressants effectively reduce symptoms of generalized anxiety disorder (GAD) under trial conditions, although there is limited data on long-term usage.

GAD affects millions of people worldwide and is characterized by excessive worry about everyday issues. Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), are recognized treatments for GAD, recommended by many national bodies including the UK’s National Institute for Health and Care Excellence. However, misconceptions remain among some healthcare professionals and patients who do not realise that ‘antidepressants’ have wider uses beyond depression, while the term also carries stigma for many people.

The review analyzed 37 randomized controlled trials with over 12,000 participants, comparing antidepressants to a placebo.  Most trials were primarily conducted in high-income countries, including the United States of America and various European countries, and recruited adults of both sexes. In most cases, there were slightly more female participants (~60%) which reflects the clinical prevalence of GAD.

Results showed that antidepressants were more effective than placebo in reducing anxiety symptoms, with a 41% higher response rate among those taking the medication compared to those taking a placebo. The review found no significant difference in dropout rates between those taking antidepressants and those taking a placebo, indicating that these medications are generally well-tolerated.

“We don’t have enough evidence to say how effective they may be in patients with GAD alongside other mental health conditions, which is much more common in clinical practice. Most of the patients I see with GAD also have other mental health conditions, so future trials should investigate the effects of different treatment strategies on patients with multiple conditions."

The review also highlights the lack of data on the long-term effects of antidepressants. Most included trials lasted between 4 to 12 weeks, with no long-term follow-up.

"We don’t have enough information on the potential long-term benefits and harms of antidepressants, even though people often take them for years,” says first author Katarina Kopcalic, who conducted the review at Western University. “This is an area that needs further exploration in future trials.” 

Despite these limitations, the review delivers a clear message: antidepressants are effective for managing GAD, particularly for patients who do not respond well to non-pharmacological treatments. However, more independent, long-term research is needed to understand their full impact, especially in patients with multiple conditions.

Calorie labelling leads to modest reductions in selection and consumption

4 months 3 weeks ago

A new Cochrane review has found that calorie labelling of food on menus and products leads people to choose slightly fewer calories.

The research team, led by scientists from UCL, Bath Spa University, the University of Cambridge and the University of Oxford, examined evidence from 25 studies on the impact of calorie labelling on food selection and consumption. They found that calorie labels in supermarkets, restaurants and other food outlets led to a small reduction in the calories people selected and purchased. The average reduction was 1.8%, which would equate to 11 calories in a 600 calorie meal – or around two almonds.

Small daily changes in energy consumption can have meaningful effects if sustained long-term, and most adults tend to gain weight as we age. A UK government report estimated that 90% of 20-40 year olds in England will gain up to 9kg over ten years, and that reducing daily energy intake by 24 calories per day – roughly 1% of the recommended intake for adults – would prevent this increase.

Our review suggests that calorie labelling leads to a modest reduction in the calories people purchase and consume.

This may have some impact on health at the population level, but calorie labelling is certainly no silver bullet. Our previous version of this review from 2018 reported a potentially larger effect, but was inconclusive because there was significant uncertainty over the results. This update has reduced that uncertainty, and we can now say with confidence that there is very likely a real, albeit modest, effect.

- Dr Gareth Hollands, senior author, from the UCL Social Research Institute, also Senior Visiting Fellow at the University of Cambridge.

The new update compiles evidence from 25 studies with a strong emphasis on real-world field settings, with 16 of the studies being conducted in restaurants, cafeterias, and supermarkets. The studies that were analysed encompassed over 10,000 participants from high-income countries including Canada, France, the United Kingdom and the USA. Only two of the studies included alcoholic drinks, and their results were too uncertain to draw any meaningful conclusions.

This review strengthens the evidence that calorie labelling can lead to small but consistent reductions in calorie selection.

While the overall impact on individual meals or food purchases may be modest, the evidence is robust. The cumulative effect at a population level could make a meaningful contribution to public health, especially as calorie labelling becomes more widespread.

- Dr Natasha Clarke, lead author, from Bath Spa University, who began the project at the University of Cambridge. 

While calorie labelling shows promise, concerns remain about its possible impact on people at risk of disordered eating. The review noted a lack of data in the included studies on possible harms, including mental health impacts, and the authors recommend future research to assess this.

“Calorie labelling to reduce the calories that people consume remains somewhat contentious, both in terms of whether it has any effect, and whether potential benefits outweigh potential risks or harms,” says Gareth. “We can now say with considerable confidence that it does have a small but potentially meaningful effect on people’s food choices. Labelling may therefore have a useful role, ideally alongside a broader set of approaches that place more onus on industry rather than individuals, such as taxes, marketing restrictions and reformulation. However, we should not expect miracles, and any implementation of calorie labelling must balance the many potential positive and negative impacts of such policies.”

Cochrane's Future of Evidence Synthesis Programme: A Transformation

4 months 3 weeks ago
Cochrane’s Future of Evidence Synthesis Programme has brought about some transformational changes

The arrival of 2025 means that we are now wrapping up our Future of Evidence Synthesis Programme, with several projects now closed and a few more due to wrap up by April 2025.

All aspects of the programme were designed to ensure that Cochrane is well-placed to meet rapidly shifting needs and challenges in global healthcare. It has been an ambitious programme that has introduced some important changes to how Cochrane develops, publishes, and shares its reviews.

A New Model for Synthesising Evidence

At the heart of this transformation is Cochrane’s new model for producing Cochrane evidence syntheses. The model retains many of the strengths that Cochrane’s reputation has been built on and added some new elements that will help to ensure Cochrane is sustainable and focused on major global health challenges now and into the future.

Evidence Synthesis Units and Thematic Groups

A key structural change has been the creation of Cochrane Evidence Synthesis Units and Thematic Groups, to help us address the world’s urgent health challenges more efficiently and collaboratively.

Cochrane Thematic Groups are topic-based collectives with specialist knowledge and expertise. They help identify priority areas, engage with key stakeholders, harness Cochrane’s global volunteer network and support the production and dissemination of high-quality Cochrane evidence syntheses. We have set up twelve Thematic Groups, each led by experts in their respective fields. Find out more.

Cochrane Evidence Synthesis Units are collaborative, multi-topic research groups, created to support delivery of trusted, timely Cochrane evidence to address major global health challenges. The geographic spread of the five new units reflects Cochrane’s commitment to producing evidence that helps to improve people’s health worldwide. Find out more.

Centralised Editorial Service

Cochrane’s Central Editorial Service has been scaled up to ensure an independent, and rigorous quality assurance process across all manuscripts and a more consistent experience for author teams. The Editorial Service works with Cochrane group members who contribute their expertise throughout the peer review process. Importantly, the centralisation eliminates conflicts of interest, with clear separation between manuscript development and editorial decisions. This ensures Cochrane reviews remain impartial, credible, and scientifically robust.

Simplifying the author journey

Cochrane’s authors are critical to Cochrane success – past and future – so through the Future of Evidence Synthesis programme we have introduced tools to make their experience smoother. The adoption of the Focused Review Format prioritises simplicity and clarity in review writing. This format reduces complexity for authors, speeds up review development time, and ensures Cochrane reviews communicate a clear message.

A major upgrade to RevMan, Cochrane’s authoring platform, has also taken place. The introduction of ‘study centric data’ streamlines data management, enabling authors to easily enter, reuse, and export data, reducing errors and saving time. Gone are the days of cumbersome back-and-forth data handling; authors can now focus on crafting compelling, well-supported reviews that inform global health decisions. Cochrane has expanded its resources for authors with dedicated roles, such as Evidence Synthesis Development Editors, to guide authors of high-priority review from planning to submission and offer expert advice on everything from scoping reviews to evaluating evidence quality. This hands-on assistance ensures Cochrane’s highest-priority reviews meet the highest standards while maintaining a personal touch.

Updated reporting standards and improved accessibility

A shift to the PRISMA guidelines for systematic reviews signals another step forward. Cochrane reviews now align with international standards, making them easier to produce and more user-friendly for their global audience. This transition reduces administrative burden while enhancing the clarity and accessibility of Cochrane’s output.

Additionally, systematic reviews produced in RevMan now come with downloadable data packages in formats like CSV, broadening the potential for research collaboration and reducing duplication. These changes solidify Cochrane’s commitment to Open Science, making its data transparent and accessible for the wider research community.

Global impact and inclusivity

With a renewed focus on inclusivity Cochrane seeks to ensure that its evidence reaches and benefits people everywhere. Evidence Synthesis Units in regions such as Nigeria and India reflect a deeper commitment to continue ensuring that our geographic representation in evidence synthesis is widespread and equal. Collaborations with global organisations like the World Health Organization (WHO) and local stakeholders in lower- and middle-income countries guarantee that Cochrane’s work addresses health inequities and meets diverse regional needs.

Inclusivity extends into the review process itself. With improved tools and simplified reporting standards, researchers from underrepresented regions and early-career scientists face fewer procedural barriers, increasing opportunities for collaboration and contribution to prioritise reviews that tackle globally significant issues.

Toward a brighter future for health evidence

The changes implemented as part of the Future of Evidence Synthesis Programme are not just about improving internal efficiencies, they are about creating a lasting impact. By adapting to a fast-changing scientific landscape, Cochrane can continue to contribute meaningfully to global health challenges now and in the future.

At a time of significant uncertainty, the Cochrane community has played an important role in the transformation. Together, community members have shown great resilience, ensuring these improvements address the real-world needs of practitioners, policymakers, and patients. These advancements not only secure Cochrane’s future but reaffirm its role as a bedrock of reliable health evidence in an uncertain world. For everyone who relies on trusted, accessible, and impactful health evidence, the changes brought by the Future of Evidence Synthesis programme are already making a difference. Cochrane is now better equipped than ever to deliver on its mission of improving health decisions - and people’s lives - worldwide.
