HCQ for COVID-19
1st treatment shown to reduce risk in March 2020
 
*, now known with p < 0.00000000001 from 421 studies, recognized in 42 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
3,800+ studies for 60+ treatments. c19hcq.org
Low-dose prophylaxis RCT with low-risk healthcare workers in India, showing no significant differences. Symptomatic case results are not provided. Followup was over 6 months, however treatment ended after 3 months. 21% of patients discontinued treatment before 3 months (Table S2).
risk of progression, 196.2% higher, RR 2.96, p = 1.00, treatment 1 of 211 (0.5%), control 0 of 203 (0.0%), continuity correction due to zero event (with reciprocal of the contrasting arm), ICU/HDU.
risk of hospitalization, 51.9% lower, RR 0.48, p = 0.62, treatment 1 of 211 (0.5%), control 2 of 203 (1.0%), NNT 196.
risk of case, 14.2% lower, RR 0.86, p = 0.73, treatment 11 of 211 (5.2%), control 12 of 203 (5.9%), NNT 143, adjusted per study, odds ratio converted to relative risk, confirmed cases, multivariable.
risk of case, 5.7% lower, RR 0.94, p = 0.90, treatment 12 of 211 (5.7%), control 12 of 203 (5.9%), NNT 446, adjusted per study, odds ratio converted to relative risk, multivariable.

Ethics approval This study involves human participants and was approved by The George Institute Ethics Committee (reference number: 08-2020). Participants gave informed consent to participate in the study before taking part. Provenance and peer review Not commissioned; externally peer reviewed. Data availability statement Data are available upon reasonable request. Deidentified patient data will be made available beginning 6 months after publication of the study and ending at 2 years. All requests for data sharing must be accompanied by a formal request, a study proposal with clear statement of aims and hypotheses and a statistical analysis plan. All applications will be assessed by the HOPE Management Committee. Applications from investigators with suitable academic capability to conduct the proposed work will be given consideration. Any proposal will require approval from the ethics committee which approved the conduct of this trial prior to sharing of any patient data. If a proposal is approved, a signed data transfer agreement will be required before data sharing. Supplemental material This content has been supplied by the author(s).
