Cochrane Russia helps to prepare new systematic reviewers

Thu, 10/06/2016 - 18:23

Successful two-day workshop increases awareness of evidence-based medicine and Cochrane

The Kazan Federal University, the home of Cochrane Russia, hosted a two-day workshop on the first step of conducting a systematic review; from registering the title to drafting the protocol. The workshop was intended for health professionals, researchers, academics, and teachers, willing to commit to development of Cochrane systematic reviews as authors or peer reviewers, and to Cochrane activities in Russia.

The event was a great success, with 15 graduating the two-day course and significant media coverage of the event and Cochrane’s work. Several news and TV stations covered the event, helping to increase the profile of Cochrane in Russia and inform the general public about the importance of evidence-based medicine.

Use of Cochrane Reviews to inform WHO guidelines

Fri, 09/30/2016 - 15:34

So far this year, 90% of the 2016 WHO guidelines contain Cochrane Evidence

Cochrane exists so that healthcare decisions get better. During the past 20 years, Cochrane has helped to transform the way health decisions are made. Cochrane contributors - 37,000 from more than 130 countries - work together to produce credible, accessible health information that is free from commercial sponsorship and other conflicts of interest. Many of our contributors are world leaders in their fields - medicine, health policy, research methodology, or consumer advocacy - and our groups are situated in some of the world's most respected academic and medical institutions. Our work is recognized as representing an international gold standard for high quality, trusted information.

Cochrane has been a non-governmental organization in official relations with the World Health Organization (WHO) since 2011. WHO develops global health guidelines, which are of a high methodological quality and are developed through a transparent, evidence-based decision-making process. Ensuring there is an appropriate use of evidence within these guidelines, represents one of the core functions of WHO.

The percentage of Cochrane Reviews used in WHO guidelines have been steadily raising. So far for 2016, Cochrane Reviews have been included in 90% of the WHO guidelines, which surpasses last year’s 75% inclusion rate. As of 26 September 2016, 474 reviews from Cochrane Review Groups have been used to inform 160 World Health Organization accredited guidelines and other evidence-based recommendations published between 2008 and 2016. Of the 160 WHO guidelines and other evidence-based recommendations that have used Cochrane reviews to inform their guidance, 14 have used over 10 reviews in any one guideline.

Cochrane’s partnership with WHO is helping to put our high quality evidence into guidelines that will have an impact upon health policies and clinical practise worldwide. It’s also a testament to the important and hard work that many in the Cochrane community are putting forward.

Featured Review: Population-level interventions in government jurisdictions for dietary sodium reduction

Thu, 09/15/2016 - 17:52

National government initiatives have the potential to achieve population-wide reduction in salt intake

In almost all countries worldwide, most people eat too much salt. This can cause high blood pressure, which can lead to health problems, such as heart disease and stroke. To reduce the amount of salt eaten, governments in many countries have developed national salt reduction initiatives. These initiatives may be individually oriented, such as providing education about salt, or structurally oriented, to improve or offset the deficiencies which prevent people from obtaining food with lower salt. As the number of population-based initiatives to reduce salt rise worldwide, it is important for policy-makers to identify which population-level intervention are impactful and cost-effective.

A team of Cochrane authors based in Australia and Canada worked with Cochrane Public Health to examine whether national salt reduction initiatives have been effective in reducing the amount of salt consumed in those populations. Fifteen national initiatives including more than 260,0000 people were included, with 10 initiatives providing sufficient date for quantitative analysis. These were mostly conducted in high-income countries. The quality of the data was rated to be very low given the nature of the interventions does not lend to using controlled study design.

Population-level interventions in government jurisdictions for dietary sodium reduction have the potential to result in population-wide reductions in salt intake from pre-intervention to post-intervention, particularly if they have more than one intervention activity and incorporate interventions of a structural nature (e.g. large-scale efforts to lower the salt content of food products at the time of production), and particularly amongst men. Implementation of future initiatives should embed more effective means of evaluation to help us better understand the variation in the effects.

This Cochrane Review excluded a larger number of national salt reduction strategies because the data lacked pre and/or post data points which are needed to examine the impact of the intervention. There were 15 included initiatives in the review but with a wide variation in the elements they included, as well as the quality of evidence in their evaluation. For these reasons, it is difficult to interpret the current evidence and warrants more research. This review provides some evidence that national sodium reduction initiatives that are multi-component and include activities of a structural nature, such as policies to lower the salt levels in food in specific settings, appear to be more effective than single-component initiatives, such as information campaigns.

2019 Journal Impact Factor for Cochrane Database of Systematic Reviews is 7.890

Thu, 06/30/2016 - 10:54

 The 2019 Journal Citation Report (JCR) has just been released by Clarivate Analytics, and we are delighted to announce that Cochrane Database of Systematic Reviews (CDSR) Journal Impact Factor is now 7.890.

This is an increase on the 2018 Journal Impact Factor, which was 7.755.

The CDSR Journal Impact Factor is calculated by taking the total number of citations in a given year to all Cochrane Reviews published in the past 2 years and dividing that number by the total number of Reviews published in the past 2 years. It is a useful metric for measuring the strength of a journal by how often its publications are cited in scholarly articles.

Some highlights of the CDSR 2019 Journal Impact Factor include:

  • The CDSR is ranked 10 of the 165 journals in the Medicine, General & Internal category
  • The CDSR received 67,763 cites in the 2019 Journal Impact Factor period, compared with 67,607 in 2018
  • The 5-Year Journal Impact Factor is 7.974 compared with 7.949 in 2018

The main Journal Impact Report and the Cochrane Review Group reports will be delivered in August 2020.

Wearing Cochrane evidence: a personal story of impact

Thu, 01/07/2016 - 13:08

Rebecca Selby, a mum of four, shares how a Cochrane Review impacted her family.

When I unexpectedly went into premature labour with our second son at a little under 32 weeks' gestation, I was given steroid injections to give his lungs the best possible chance in the outside world. George spent almost a month in intensive care when he was born, spending some time on full ventilation and on continuous positive airway pressure (CPAP), to help him to breathe. Throughout his time in hospital, George developed a series of infections and I am sure that the boost to his lungs from the steroid medication is what gave him the ability to overcome these difficulties and ultimately saved his life. It is unlikely that George would be our 12-year-old little boy now without the treatment that he received, a fact for which we will all be eternally grateful!

In September 2015 I started at The University of Manchester to study Biology with Science and Society. I learned about the meaning behind the Cochrane logo while conducting research over the course of my studies. Each horizontal line within the logo represents the results of one study, while the diamond shape represents the combined results. The best estimate of whether the treatment is effective or harmful is established in this way, through systematic review. In the Cochrane logo, the diamond sits clearly to the left of the vertical line. The diamonds’ position represents that treatment does not contribute to negative outcomes, which indicates that the treatment is beneficial. The visual representation of these results, the “forest plot”, within the Cochrane logo illustrates a systematic review (originally published by Crowley et al. and subsequently updated) that was influential in increasing use of corticosteroids in women who are about to give birth prematurely. This simple intervention has probably saved thousands of premature babies – including George.

I was really drawn to the symbolism in this logo and the personal connection I have with it. The fact that all signs from the individual trials indicated that the treatment had little to no benefit until you step back and put all of the trial outcome information together in a systematic review is brilliant.  Sometimes you need to step back and look at the bigger picture!  My husband has since incorporated the inner circle of the Cochrane logo into a tattoo, as a physical reminder of our own little miracle of medical science.

Thank you to all the Cochrane reviewers for making a difference to the lives of families, including mine.

Updated review: Insufficient evidence for use of Omega-3 supplements in treating depression

Thu, 11/05/2015 - 00:45

Updated Cochrane research concludes that there is insufficient evidence for the use of Omega-3 fatty acid supplements in treating major depressive disorder.

Omega-3 fatty acids are widely thought to be essential for good health and are naturally found in fatty fish such as mackerel; other seafood; and some nuts and seeds.

Omega-3 fatty acids have been widely promoted globally for a variety of health concerns, and are readily available as an over-the-counter supplement. These supplements have hugely increased in popularity over the last decade, together with a range of other supplements including ginseng, garlic, green tea, vitamins, minerals, and herbal products.

There have been various studies that have suggested a role for Omega-3 fatty acid supplementation in treating major depressive disorder. Adults with major depressive disorders are characterized by depressed mood or a lack of pleasure in previously enjoyed activities for at least two weeks, in the absence of any physical cause, that impact on everyday life.

Figures published in 2018 estimated prevalence rates for major depressive disorders of 163 million cases in 2017, and global incidence rates of 242 million cases, resulting in 33 million years lived with disability globally, an increase of 12.6% since 2007.


This updated Cochrane Review, published recently in the Cochrane Library, gathered together data from 28 randomized trials involving a total of 1944 participants. The trials investigated the impact of giving an Omega-3 fatty acid supplement in a capsule form and compared it to a dummy pill. In one study, involving 40 participants, researchers also investigated the impact of the same supplementation compared to an anti-depressant treatment.

The Cochrane authors found that, whilst people who were given Omega-3 fatty acids reported lower symptom scores than people with the dummy pill, the effect was small and there were important limitations that undermined their confidence in the results. Their analyses showed that although similar numbers of people experienced side effects, more data would be required to understand the risks of taking Omega-3 fatty acids.



Lead author Katherine Appleton from Bournemouth University said, “This is an update of an existing Cochrane Review, using the same methods as we previously used, with some refinements. The update includes 8 randomised controlled trials published since 2015, in addition to the 20 trials included in the previous review.

Our conclusions however remain unchanged. We found a small-to-modest positive effect of Omega-3 fatty acids compared to placebo for depressive symptomology, but the size of this effect is unlikely to be meaningful to people with depression, and we considered the evidence on which this conclusion was based to be of low or very low quality. All studies contributing to our analyses were of direct relevance to our research question, but most of these studies are small and of low quality. We also found insufficient evidence to clearly determine the effects of omega-3 oils on negative side effects or when compared with anti-depressants.”

She added, “At present, we just don’t have enough high-quality evidence to determine the effects of Omega-3 fatty acids as a treatment for major depressive disorder. It’s important that people who suffer from depression are aware of this, so that they can make more informed choices about treatment.”
