The COVID-NMA initiative
A living mapping and living systematic review of Covid-19 trials

COVID-NMA is an international research initiative supported by the WHO and Cochrane.

We provide a living mapping of COVID-19 trials. We are also conducting living evidence synthesis on preventive interventions, treatments and vaccines for COVID-19 to assist decision makers.

See the description of our model here and our living review protocol here.
