We aimed to investigate whether hospitalizations of patients tested positive for COVID-19 antibodies are associated with reduced in-hospital mortality. Of the 2,459 patients admitted due to COVID-19 and tested for antibodies, 937 (38.1%) had positive tests. After adjustment for patient characteristics and treatments, patients with positive COVID-19 antibody test had lower in-hospital mortality compared to those with negative test results (odds ratio [OR]: 0.62; 95% confidential interval [95% CI] 0.46-0.83, P=0.001). In conclusions, positive COVID 19 antibody test results were associated with the reduced risk of in-hospital mortality for COVID-19 patients. This article is protected by copyright.
