One of the early studies published on HCQ as a possible treatment for COVID-19 was [https://jornalggn.com.br/sites/default/files/2020/04/paper-preventsenior.pdf Empirical treatment with hydroxychloroquine and azithromycin for suspected cases of COVID-19 followed-up by telemedicine] which was published as a preprint on April 15<ref name=c19study/> by the Prevent Senior Institute in São Paulo, Brazil. The study had several limitations that made it less than ideal... it wasn't randomized and it had to assume that patients who were exhibiting flu-like symptoms during São Paulo's SARS-CoV-2 pandemic had contracted SARS-CoV-2 (testing wasn't widely available at the time), but the study also had several strengths. Unlike retrospective studies like the VA study, it had a natural control group - it offered to give HCQ and azithromycin to 636 symptomatic outpatients, 412 of whom accepted the treatment (the treatment group) and 224 of whom refused the medications (the control group). It also used HCQ ''early'' which is when antivirals are most effective and the patients were monitored by telemedicine<ref name =Brazilstud/> (unlike Boulware's study).
