HCQ for COVID-19
1st treatment shown to reduce risk in March 2020, now with p < 0.00000000001 from 419 studies, recognized in 46 countries.
No treatment is 100% effective. Protocols combine treatments.
5,100+ studies for 112 treatments. c19hcq.org
Analysis of 80 SLE patients diagnosed with COVID-19, showing the frequency of hospitalisation did not differ between individuals using an antimalarial versus non-users (55% (16/29) vs 57% (29/51), p=ns. Authors suggest that the dosage used may be too low to reach therapeutic levels.
This study is excluded in the after exclusion results of meta analysis: not fully adjusting for the baseline risk differences within systemic autoimmune patients; unadjusted results with no group details.
risk of hospitalization, 3.0% lower, RR 0.97, p = 0.88, treatment 16 of 29 (55.2%), control 29 of 51 (56.9%), NNT 59.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
