HCQ is effective for COVID-19. The probability that an ineffective treatment generated results as positive as the 235 studies to date is estimated to be 1 in 6 quadrillion (p = 0.00000000000000018).
Early treatment is most successful, with 100% of 29 studies reporting a positive effect (13 statistically significant in isolation) and an estimated reduction of 65% in the effect measured (death, hospitalization, etc.) using a random effects meta-analysis, RR 0.35 [0.25-0.50].
92% of Randomized Controlled Trials (RCTs) for early, PrEP, or PEP treatment report positive effects, the probability of this happening for an ineffective treatment is 0.0017.
There is evidence of bias towards publishing negative results. 88% of prospective studies report positive effects, and only 73% of retrospective studies do.
Studies from North America are 3.8 times more likely to report negative results than studies from the rest of the world combined, p = 0.0000000015.

Introduction
We analyze all significant studies concerning the use of HCQ (or CQ) for COVID-19. Search methods, inclusion criteria, effect extraction criteria (more serious outcomes have priority), all individual study data, PRISMA answers, and statistical methods are detailed in Appendix 1. We present random-effects meta-analysis results for all studies, for studies within each treatment stage, for mortality results only, after exclusion of studies with critical bias, and for Randomized Controlled Trials (RCTs) only. Typical meta analyses involve subjective selection criteria and bias evaluation, requiring an understanding of the criteria and the accuracy of the evaluations. However, the volume of studies presents an opportunity for an additional simple and transparent analysis aimed at detecting efficacy.
If treatment was not effective, the observed effects would be randomly distributed (or more likely to be negative if treatment is harmful). We can compute the probability that the observed percentage of positive results (or higher) could occur due to chance with an ineffective treatment (the probability of >= k heads in n coin tosses, or the one-sided sign test / binomial test). Analysis of publication bias is important and adjustments may be needed if there is a bias toward publishing positive results. For HCQ, we find evidence of a bias toward publishing negative results.
Figure 2 shows stages of possible treatment for COVID-19. Pre-Exposure Prophylaxis (PrEP) refers to regularly taking medication before being infected, in order to prevent or minimize infection. In Post-Exposure Prophylaxis (PEP), medication is taken after exposure but before symptoms appear. Early Treatment refers to treatment immediately or soon after symptoms appear, while Late Treatment refers to more delayed treatment.
    
  
Figure 2. Treatment stages.
Results
Figure 3, Figure 4, and Table 1 show results by treatment stage, and Figure 5 shows a forest plot for a random effects meta-analysis of all studies. Figure 6 shows a forest plot restricted to mortality results only.
Early treatment.
100% of early treatment studies report a positive effect, with an estimated reduction of 65% in the effect measured (death, hospitalization, etc.) from the random effects meta-analysis, RR 0.35 [0.25-0.50].
Late treatment.
Late treatment studies are mixed, with 72% showing positive effects, and an estimated reduction of 23% in the random effects meta-analysis. Negative studies mostly fall into the following categories: they show evidence of significant unadjusted confounding, including confounding by indication; usage is extremely late; or they use an excessively high dosage.
Pre-Exposure Prophylaxis.
77% of PrEP studies show positive effects, with an estimated reduction of 29% in the random effects meta-analysis. Negative studies are all studies of systemic autoimmune disease patients which either do not adjust for the different baseline risk of these patients at all, or do not adjust for the highly variable risk within these patients.
Post-Exposure Prophylaxis.
86% of PEP studies report positive effects, with an estimated reduction of 34% in the random effects meta-analysis.
