Prospective study of 187 telemedicine patients in Brazil. 74 presenting with moderate symptoms were offered treatment with HCQ+AZ, 12 did not accept HCQ (taking AZ only), forming a control group. There was lower hospitalization and improved recovery with treatment. There appears to be different group sizes in the text and tables without explanation (maybe a typo). RBR-658khm.
This study is excluded in the after exclusion results of meta
analysis:
unadjusted results with no group details.
risk of hospitalization, 94.7% lower, RR 0.05, p = 0.004, treatment 0 of 60 (0.0%), control 3 of 12 (25.0%), NNT 4.0, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).

Abstract
Introduction: As a result of the coronavirus disease 2019 (COVID-19) pandemic the
year 2020 brought major changes on the delivery of health care and face to face
physician patient communication was significantly reduced and the practice of remote
telehealth care using computer technology is assuming a standard of care, particularly,
with COVID-19 patients with attempts to reduce viral spread.
Objective: To describe the clinical practice experience using telemedicine towards
COVID-19 and the respective clinical outcomes.
Methods: We performed a pilot open-label non-randomized, controlled clinical trial. The
patients were divided into four groups, according severity of symptoms: (1)
asymptomatic, (2) mild symptoms, (3) moderate symptoms and (4) severe symptoms,
and were followed up for five days, counted from the beginning of the symptoms. A drug
intervention was performed in group 3, for which the protocol followed as suggested by
the International Pulmonology Society’s consensus for adults with moderate..
