Effects of potent neutralizing antibodies from convalescent plasma in patients hospitalized for severe SARS-CoV-2 infection
RCT 86 hospitalized patients, 43 treated with convalescent plasma, not showing significant differences with treatment. Authors conclude that the most likely explanation was already high antibody titers on the day of inclusion, and they recommend treating patients early. NCT04342182.

risk of death, 3.8% lower, RR 0.96, p = 0.95, treatment 6 of 43 (14.0%), control 11 of 43 (25.6%), adjusted per study, odds ratio converted to relative risk, multivariable logistic regression.
time to discharge, 11.7% lower, relative time 0.88, p = 0.68, treatment 43, control 43, adjusted per study, multivariable Fine and Gray regression.
Effect extraction follows pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
