Abstract
We aimed to investigate whether hospitalizations of patients who tested positive for coronavirus disease 2019 (COVID-19) antibodies are associated with reduced in-hospital mortality. Of the 2459 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 with those with negative test results (odds ratio [OR]: 0.62; 95% confidential interval [95% CI] 0.46-0.83, p = 0.001). In conclusion, positive COVID-19 antibody test results were associated with the reduced risk of in-hospital mortality for COVID-19 patients.
