RCT 16,287 hospitalized patients in the UK, showing no significant differences with convalescent plasma treatment. Subgroup analysis shows better results for those treated <= 7 days from symptom onset.
risk of death, no change, RR 1.00, p = 0.95, treatment 1,399 of 5,795 (24.1%), control 1,408 of 5,763 (24.4%), NNT 345, day 28, primary outcome.
risk of no hospital discharge, 1.0% higher, RR 1.01, p = 0.57, treatment 1,963 of 5,795 (33.9%), control 1,941 of 5,763 (33.7%), inverted to make RR<1 favor treatment, day 28.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

Background Many patients with COVID-19 have been treated with plasma containing anti-SARS-CoV-2 antibodies. We aimed to evaluate the safety and efficacy of convalescent plasma therapy in patients admitted to hospital with COVID-19. Methods This randomised, controlled, open-label, platform trial (Randomised Evaluation of COVID-19 Therapy [RECOVERY]) is assessing several possible treatments in patients hospitalised with COVID-19 in the UK. The trial is underway at 177 NHS hospitals from across the UK. Eligible and consenting patients were randomly assigned (1:1) to receive either usual care alone (usual care group) or usual care plus high-titre convalescent plasma (convalescent plasma group). The primary outcome was 28-day mortality, analysed on an intention-to-treat basis. The trial is registered with ISRCTN, 50189673, and ClinicalTrials.gov, NCT04381936.
