INR = international normalized ratio; PRBC = packed red blood cells; FFP = fresh frozen plasma; OR = operating room; HLOS = hospital length of stay.

Median and interquartile range reported for continuous variables.

P value is based on the Wilcoxon rank sum test for continuous variables and χ² or Fisher exact test for categorical variables.

^*During the first abdominal surgery.

^†In those whose fascia was closed before discharge.
