 In this study, researchers examined the association between SARS, CLV, Tuvarimia and mortality in COVID-19 hospitalized patients during different epidemic periods. They found that patients who tested positive for SARS, CLV, Tuvarimia were more likely to die than those who tested negative. This suggests that SARS, CLV, Tuvarimia may serve as a predictor of mortality in COVID-19 patients. This article was authored by Andrea Giacomelli, Alena Regini, Valeria McKaylee, and others.
