Retrospective 303 remdesivir patients and 303 matched controls showing significantly faster clinical improvement, and lower (but not statistically significant) mortality.

Garibaldi et al., 11/20/2020, retrospective, USA, North America, preprint, 10 authors.
risk of death, 20.0% lower, RR 0.80, p = 0.44, treatment 23 of 303 (7.6%), control 45 of 303 (14.9%), adjusted per study.
risk of no improvement at day 28, 35.0% lower, RR 0.65, p < 0.001, treatment 52 of 303 (17.2%), control 80 of 303 (26.4%), adjusted per study.

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.
