Summary of the effects of all available interventions compared to standard care

The information presented in the figure below comes from a living network meta-analysis that combines all the available evidence on drug therapies for COVID-19. This statistical approach allows us to obtain estimates of effect for all potential comparisons, even those that have not been compared head-to-head in trials. We present the most trustworthy estimates of absolute effect for all available drug therapies for COVID-19 versus standard care. The colours distinguish between the most beneficial and harmful interventions compared to standard care, while the shading of cells indicates the certainty of the evidence of a particular drug based on the GRADE approach.
