Multivariable linear regression for prediction of elevated mortality by surgeons. Surgeon experience (< 5 y or ≥ 5 y) was included as a forced variable.

Surgeon experience ≥5 y	−3.61	−9.99 to 2.77	0.265
Age	0.28	0.07 to 0.50	0.011
Hypertension	−7.07	−13.64 to −0.50	0.035
Ascites	19.74	11.49 to 27.99	<0.001
Sepsis	16.82	6.79 to 26.85	0.001
White blood cell count	0.70	0.26 to 1.14	0.002
Albumin level	−6.81	−11.13 to –2.48	0.002
