Values are presented as mean±standard deviation or number (%).

COVID-19, coronavirus disease 2019; AST, aspartate aminotransferase; ALT, alanine aminotransferase; BUN, blood urea nitrogen; LDH, lactate dehydrogenase.

aLymphocytopenia is defined as a lymphocyte count of less than 1,500 cells per cubic millimeter. bP-value by chi-square test.

P-value was calculated by ANOVA.
