Retrospective study comparing 122 remdesivir patients and 211 lopinavir/ritonavir patients, showing higher rates of clinical improvement with remdesivir and lower mortality (not statistically significant).
all patients, 48.9% lower, RR 0.51, p = 0.18, treatment 5 of 122 (4.1%), control 17 of 211 (8.1%), odds ratio converted to relative risk.
SpO2<95%, 58.0% lower, RR 0.42, p = 0.13, treatment 4 of 82 (4.9%), control 14 of 119 (11.8%), odds ratio converted to relative risk.
no clinical improvement, 56.5% lower, RR 0.44, p = 0.01, treatment 9 of 122 (7.4%), control 36 of 211 (17.1%), odds ratio converted to relative risk.

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.
