Small RCT of nasopharyngeal viral load not showing significant differences. The rate of reduction for HCQ was 0.24 [0.03-0.46] RNA copies/mL/24h, and 0.14 [-0.10-0.37] for the control group (71% faster with HCQ but not statistically significant with the small sample size of 27 HCQ and 26 control patients). Analysis only over 96 hours.NCT04316377
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.

risk of death, 3.7% lower, RR 0.96, p = 1.00, treatment 1 of 27 (3.7%), control 1 of 26 (3.8%).
improvement in viral load reduction rate, 71.0% lower, relative rate 0.29, p = 0.51, treatment 27, control 26.
