Abbreviations: PSM Propensity score–matching analysis; HR Hazard ratio; CI Confidence interval; N/L Ratio of neutrophils to lymphocytes; APACHE II Acute Physiology And Chronic Health Evaluation II. The following variables were incorporated into Cox proportional-hazard model analysis: sex, age, duration of methylprednisolone use (days), average daily dose of methylprednisolone, hypertension, N/L, D-dimer, and APACHE II score
