Risk score adjustment^a

Risk factor	Original β coefficient	Original score	Adjusted β coefficient	Adjusted score
Age per 10 years (40–90)	0.11	0.5	–	0.5
Female with ASA 1–2	0	0	–	0
Female with ASA 3–4	0.52	2.5	–	2.5
Male (any ASA)	0.88	4.5	–	4.5
BMI per 10 points (20–50)	0.39	2	–	2
Multivisceral resectiona	0.42	2	–	2
Open surgery	0.49	2.5	–	2.5
High-volume DP-CAR centerb	–	–	− 1.31	− 6.5
Intercept	− 2.82	–	− 3.96	–
Total		6–23.5		0–23.5

Model coefficients were obtained from the original design dataset7 to determine the risk score by rounding and multiplication. The intercept was adjusted for the risk of 90-day mortality in the design cohort (n = 71); a coefficient for high-volume center was added

ASA, American Society of Anesthesiologists; BMI, body mass index; DP-CAR, distal pancreatectomy with celiac axis resection

^aDefinition: other than celiac axis, gallbladder, pancreas, or spleen
