No difference was found in the primary endpoint, which was the incidence of death at 28 days (26.8% hydroxychloroquine vs. 25% usual care, 95% CI 0.96-1.23; p=0.18). Be aware that there are no proven treatments for COVID-19 and no vaccine. The aim of our Safety Public Assessment Reports is to present evidence-based assessments of safety issues for a particular drug or drug class. The results for cardiovascular mortality in the long term on-treatment analysis appeared inconsistent across the available databases, with increased risk in two US databases but not in CPRD, but overall were increased in the hydroxychloroquine group when a meta-analysis was conducted: pooled hazard ratio (HR) 1.65 (95% confidence interval (CI) 1.12 to 2.44).
