Dichotomizing the 2 predictors of propensity to receive a JP drain as pre-transplant serum albumin < vs. ≥3.4 g/dL and CIT as < vs. ≥24 h, the observed percentages of patients who developed any hematoma were as follows: 21.4% (3/14) vs. 33.3% (3/9) for CIT < vs. ≥24 h among patients with a normal serum albumin (≥3.4 g/dL); and 40.0% (6/15) vs. 64.7% (11/17) for CIT < vs. ≥24 h among patients with a low serum albumin (< 3.4 g/dL). This evidence concerns the gene ALB and hematoma.
