Meta-analysis of randomized trials showed that Hydroxychloroquine use was associated with an 11% increase in the mortality rate
Hydroxychloroquine (HCQ) was used off-label despite the absence of evidence documenting its clinical benefits. Since then, a meta-analysis of randomized trials showed that HCQ use was associated with an 11% increase in the mortality rate. We aimed to estimate the number of HCQ-related deaths worldwide.
