AST = serum aspartate aminotransferase; ALT = serum alanine aminotransferase; DOI = days postonset of illness; IQR = interquartile range; IU/L = international unit/liter. Figures in the parenthesis indicate percentages unless otherwise indicated. P value was calculated using Mann–Whitney U test for age and DOI, and χ2 test for all categorical variables.
