    The Copenhagen Trial Unit

    Welcome to the Copenhagen Trial Unit – the CTU.

    The CTU is a clinical intervention research unit conducting clinical research within all specialities.

    We offer flexible collaboration and consulting at all stages of clinical research.

    We provide expertise and infrastructure in planning, conduct, analysis, and interpretation of randomised clinical trials, including development of trial methodology and education.

    The CTU has been involved in the conduct of more than 500 protocols for systematic reviews, which has materialised in the publication of more than 300 systematic reviews published within and outside The Cochrane Collaboration. The CTU has developed methodology and software for conducting Trial Sequential Analyses (TSA).

    We provide advice, support, and full collaboration during the protocol and systematic review development. We offer expertise in search strategy design, conduct literature searches for systematic reviews, and offer help with or conduct of meta-analyses.

    The CTU has been involved in the conduct of more than 130 randomised clinical trials in which more than 120,000 participants were randomised.

    The CTU hosts the Editorial Team Office of the Cochrane Hepato-Biliary Group (CHBG)) - one of the 53 global Collaborative Review Groups within The Cochrane Collaboration - as well as the Danish Clinical Research Infrastructures Network (DCRIN), the Danish coordinating hub of the Nordic Trial Alliance (NTA), and the Danish coordinating hub of the European Clinical Research Infrastructures Network (ECRIN).
