aNS = not significant at p >0.20; AST = aspartate aminotransferase; ALT = alanine aminotransferase.

bLaboratory values are those taken on first visit to a health-care provider; for continuous variables, the figures in the table are mean values.

cBacteremic patients with liver cirrhosis, acute cholangitis, and liver abscess were excluded from the analysis of liver function tests.
