A website for cluster randomised trials including stepped wedge: facilitating quality trials and methodological research

Background A cluster randomised trial is a randomised controlled trial in which groups of individuals (clusters) are randomised to treatment arms. Stepped wedge cluster randomised trials are a type of cluster randomised trial where clusters are randomised to sequences. These trial designs are important for impacting decision-making, and it is therefore important that they be well-conducted and reported. Main body In November 2018, we created a new website dedicated to cluster randomised trials, including stepped wedge designs: Conclusion We aim to keep the site updated with the latest publications and events related to cluster randomised trials, and welcome suggestions from the research community on further resources or events to add. We hope that the site will facilitate high-quality traditional and stepped wedge cluster randomised trials. Keywords: Cluster randomised trial, Group randomised trial, Stepped wedge, Website
