claim: hydroxychloroquine proves activity in hamsters and macaques infected with sars-cov-2
evidence_1: similarly, hcq prophylaxis/treatment (6.5 mg/kg) did not significantly benefit clinical outcome nor reduce sars-cov-2 replication/shedding in the upper and lower respiratory tract in the rhesus macaque disease model.", "in conclusion, hcq prophylaxis and treatment had no beneficial effect in the two animal disease models tested.")
