A US study shows that patients who use chloroquine die more often than those who do not.
According to the study, among those infected with the coronavirus who were treated with hydroxychloroquine, 27,8% died. The research refutes Jair Bolsonaro's claim that a drug, still lacking scientific proof, is effective against COVID-19.
247 Researchers at the University of Virginia (USA) conducted a retrospective analysis of the evolution of the coronavirus in 368 patients in the network of 170 clinics of the Veterans Health Administration, which serves war veterans across the country.
According to the study, among those who were treated with hydroxychloroquine, 27,8% died. Among those who took hydroxychloroquine along with azithromycin (an antibiotic), 22,1% died. Among those who did not receive the treatment, the number reached 11,4%.
In conclusion of scientific article, published on a platform preprint (Before peer review), it is stated that "no evidence was found that the use of hydroxychloroquine, with or without azithromycin, reduced the risk of mechanical ventilation in hospitalized patients with COVID-19. An association with increased overall mortality was identified in patients treated with hydroxychloroquine alone."
