  1. AKI, acute kidney injury; WBC, white blood cell; BUN, blood urea nitrogen; AST, aspartate aminotransferase; ALT, alanine aminotransferase.
  2. Continuous variables were expressed in median (interquartile range) and were compared using Wilcoxon Rank Sum Test. Category variables were expressed in number (percentage) and were compared using chi square test.
