The AllTrials campaign calls for all past and present clinical trials to be registered and their results reported. Hundreds of thousands of clinical trials have been conducted from which no or limited data have been made available; data critical to enabling doctors and regulators to make informed decisions about which treatments to use and fund. This is a serious problem for evidence-based healthcare researchers, including Cochrane, because all the evidence about a treatment is needed to understand its risks and benefits. Without a complete picture of trial results available, information is lost; bad treatment decisions may be made; financial investment into ineffective treatments are approved by governments and regulators; opportunities for better and more effective treatment are missed; and trials are repeated unnecessarily, duplicating effort and wasting resources.

AllTrials founders were Ben Goldacre, author of Bad Science, along with the charity Sense About Science; the Centre for Evidence Based Medicine in Oxford; the James Lind Initiative; the BMJ; and Cochrane.

    Campbell Collaboration

    The Campbell Collaboration is an international research network that produces and disseminates systematic reviews on the effects of interventions in the social and behavioural sciences. It seeks to improve the quality of public and private services through enhancing the evidence base for social policy and practice. It produces reviews in the areas of Crime and Justice, Education, International Development, and Social Welfare.

    Cochrane and Campbell have been closely affiliated since Campbell's establishment in 2000. In 2015 the two collaborations formalized plans to work more cooperatively and effectively together in a number of areas of common interest.

    Epistemonikos Foundation

    The Epistemonikos Foundation is a non-profit organization whose core objectives are to bring evidence closer to those making health decisions through technology and innovation, primarily via the Epistemonikos database. The database was established in 2009 and at the end of 2016 included close to 100,000 systematic reviews. Cochrane’s partnership with Epistemonikos aims at improving the knowledge base for making decisions in health care and global health policy.

    Guidelines International Network

    Guidelines International Network's (G-I-N) mission is to lead, strengthen, and support collaboration in guideline development, adaptation and implementation.

    As a major player on the global healthcare quality stage, G-I-N facilitates networking, promotes excellence, and helps our members create high quality clinical practice guidelines that foster safe and effective patient care.

    Cochrane and G-I-N formalized a partnership arrangement in 2014, agreeing to work together collaboratively to ensure that evidence is both useful and used by people making decisions about health, from individuals to clinicians to international health policy-makers from all over the world.


    The GRADE Working Group (GRADE) was established in 2000 to develop a sensible approach to assessing the certainty in a body of evidence based on systematic reviews, to developing recommendations in health care. Its work has expanded to methodology for informing other health evidence-related products and decisions, in particular guidelines, health technology assessments, policy decisions, and coverage decisions. GRADE has more than 500 international members and a growing number of globally distributed centres and networks.  Over 90 organizations worldwide have endorsed the GRADE approach, which is pre-eminent among the available frameworks.

    Joanna Briggs Institute

    Established in 1996, The Joanna Briggs Institute (JBI) is an international not-for-profit, research centre based within the Faculty of Health Sciences at the University of Adelaide, South Australia.

    The Institute collaborates internationally with over 70 entities across the world. The Institute and its collaborating entities promote and support the synthesis, transfer and implementation of evidence through identifying feasible, appropriate, meaningful and effective healthcare practices to assist in the improvement of healthcare outcomes globally.


    MAGIC (formally known as the MAking GRADE the Irresistible Choice (MAGIC) organization) is a non-profit research and innovation programme set up to make evidence summaries and recommendations that work for clinicians at the point of care and to facilitate shared decision-making with patients. Established in 2010, the MAGIC project has, among a number of other initiatives, developed the MAGICapp, a web-based platform for preparing guidelines using structured data systems and validated methods.

    Cochrane and MAGIC aim to develop and implement joint activities that support and further strengthen the use of health evidence by people making decisions about health, from the individual patient to international health policy makers, within the context of a digital and trustworthy evidence ecosystem for health care.


    Articles relating to medicine are viewed more than 180 million times per month on Wikipedia, yet less than 1 per cent of these have passed a formal peer review process. This opens up a unique opportunity for Cochrane to work with Wikipedia medical editors to transform the quality and content of health evidence available online. The partnership, formalized in 2014, supports the inclusion of relevant evidence within all Wikipedia medical articles, as well as processes to help ensure that medical information included in Wikipedia is of the highest quality and as accurate as possible. Trusted, evidence-based research can help people to make informed decisions about their own health care.

    World Health Organization

    Cochrane has been in official relations with the World Health Organization (WHO) since 2011.

    This collaboration includes the right to appoint a representative to participate, without vote, in WHO’s meetings, including at the World Health Assembly, the WHO’s decision-making body, allowing us to make expository statements on WHO health resolutions.
    This relationship gives us the opportunity to provide input on the way research evidence is identified, synthesized, assessed and used by WHO. In addition, we provide reliable summaries of health information which can be used to inform recommendations and policies.

    It promotes inter-sectoral collaboration and high-quality research between our two organizations to produce the necessary evidence to ensure policies in all sectors contribute to improving health and health equity.
