p value | |
| Mean age, years (SD) | 67.2 (12.5) | 66.0 (10.7) | p = 0.444 |
| Male, n (%) | 9 (69.23) | 44 (61.11) | p = 0.578 |
| Mean BMI, Kg/m2 (SD) | 24.8 (3.92) | 21.8 (3.49) | p = 0.008 |

| Soft pancreas, n (%) | 10 (76.92) | 26 (36.11) | p = 0.006 |
| Drain amylase on POD3, g/dL (SD) | 5,385.8 (13,096.4) | 767.73 (1,599.1) | p = 0.004 |

Abbreviations: POPF, postoperative pancreatic fistula; BMI, body mass index; PBD, preoperative biliary drainage; POD3, postoperative day 3; CRP, C-reactive protein.
The unpaired t-test was used to compare the mean values of the different subgroups, and the chi-square test was used for testing the relationships between categorical variables.
