Fig. 2From: Drain fluid and serum amylase concentration ratio is the most reliable indicator for predicting postoperative pancreatic fistula after distal pancreatectomyRelationship between changes in DAC, DAA, and DSACR with and without POPF. The Wilcoxon signed-rank test was conducted for comparisons between the groups. DAC, drain fluid amylase concentration; DAA, drain fluid amylase amount; DSACR, drain fluid and serum amylase concentration ratio; POPF, postoperative pancreatic fistula. *p < 0.05; ***p < 0.001Back to article page
