a
Long-term dialysis is that lasting more than 14 days; short-term dialysis is that lasting 14 days or less.
ALT: alanine aminotransferase; AST: aspartate aminotransferase; BUN: blood urea nitrogen; IQR: interquartile range; IQR: interquartile range; PCWP: pulmonary capillary wedge pressure; WBC: white blood cell.
