1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundA 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: https://clusterrandomisedtrials.qmul.ac.uk/ . The idea for the website emerged from the conference on Current Developments in Cluster Randomised Trials and Stepped Wedge Designs held in November 2016 at Queen Mary University of London, with the aim to provide an online resource to facilitate quality trials and methodological research on these types of trial. The website is divided into sections covering Design, Analysis and Reporting for traditional (i.e. parallel two-arm) cluster randomised trials and stepped wedge designs and contains resources in the form of hyperlinks to relevant papers along with brief explanations. A noticeboard page provides details on announcements, events, and past events.

conclusionWe 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.
