I'm assuming that none of the 1,300 veterans did die or the number of deaths would've been the focus of the article and that all of the veterans have since recovered.
FROM THE ARTICLE:
A retrospective review of the use of hydroxychloroquine on VA patients with COVID-19 showed that 28% of veterans who received the drug died; 22% of those who received hydroxychloroquine, along with the antibiotic azithromycin, also died, while just 11% of patients in the study who received standard care died.
EDIT TO ADD FROM THE ARTICLE:
But the research, which was not a rigorous scientific study but simply an analysis of data, noted that the majority of patients given the medications were severely ill, on ventilators and had underlying health conditions. They were all men, mostly black, with a median age over 65 — demographics that placed them at higher risk for severe cases of the coronavirus.
Other studies of hydroxychloroquine have shown mixed results. An ongoing study at New York University’s Grossman School of Medicine found that patients who received hydroxychloroquine, azithromycin and zinc were 44% less likely to die from COVID-19.
