Observational Study
Observational Study of Hydroxychloroquine in Hospitalized Patients with Covid-19.
Hydroxychloroquine has been widely administered to patients with Covid-19 without robust evidence supporting its use. ⋯ In this observational study involving patients with Covid-19 who had been admitted to the hospital, hydroxychloroquine administration was not associated with either a greatly lowered or an increased risk of the composite end point of intubation or death. Randomized, controlled trials of hydroxychloroquine in patients with Covid-19 are needed. (Funded by the National Institutes of Health.).
