Model 1: Adjusted for sex and age
Model 2: Adjusted for covariates included in Model 1 + clinical parameters (BMI, COVID-19 severity, CRP level, and history of heart failure, malignancy or psychiatric disease)
Model 3: Adjusted for covariates included in Model 2 + therapeutic factors (use of remdesivir, steroid, and mechanical ventilation)
Model 4: Adjusted for covariates (sex, BMI, history of psychiatric disease, use of steroid and mechanical ventilation) that were chosen by backward elimination of the covariates in Model 3
