We are thankful for the collaboration with the Core Outcome Measures in Effectiveness Trials initiative (COMET). Core Outcome Sets (COS) are a minimal set of outcomes that should be measured and reported in each trial. As many clinical trials and systematic reviews on COVID-19 are underway, COVID-19 specific COS will ensure that this evidence base will contain the key information needed by decision makers about the effects of interventions.

In April, COMET reported on the meta-Core Outcome Set for hospitalized adult patients with COVID-19 by bringing together all COS developers and agreeing on the overlap of these project. The COVID-evidence initiative has been closely collaborating with COMET to make sure all outcomes (and meta-COS) will be collected comprehensively in clear outcome domains by using an internationally recognized taxonomy.  

We are proud to announce that our first expansion module will be launched soon, dedicated to the outcomes and meta-core-outcomes reported in COVID-19 trials. We aim to provide a clear overview of all outcomes and core-outcomes being measured in COVID-19 trials in order to inform and ease the development of any future trials and living systematic reviews and meta-analyses.
