A pilot study of hydroxychloroquine in treatment of patients with common coronavirus disease-19 (COVID-19)
30 moderate hospitalized cases, all recovered. Time to RNA negative comparable. Less frequent radiological progression with HCQ but not statistically significant. One HCQ patient developed to a severe case. Treatment group 4 years older and with higher incidence of hypertension.

risk of radiological progression, 29.0% lower, RR 0.71, p = 0.57, treatment 5 of 15 (33.3%), control 7 of 15 (46.7%).
risk of viral+ at day 7, 100% higher, RR 2.00, p = 1.00, treatment 2 of 15 (13.3%), control 1 of 15 (6.7%).
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.
