COVID-19, coronavirus disease 2019; OR, odds ratio; CI, confidence interval. Lymphopenia (<1.1, ≥1.1, ×10^9/L), leukocytosis (<9.5, ≥9.5, ×10^9/L), increased alanine aminotransferase (<40, ≥41, U/L), increased lactate dehydrogenase (<214, ≥214, U/L), increased creatine kinase, and increased D-dimer (<0.5, ≥0.5, mg/L).
