Sensitivity analysis: linear regression coefficients of postoperative day 3 C-reactive protein concentrations, odds ratios of postoperative complications, and hazard ratios of all-cause mortality with respect to perioperative blood transfusion across the propensity score methods

Model	n	POD 3 CRP [B (95% CI)]	Complication [OR (95% CI)]	Overall survival [HR (95% CI)]
Unadjusted	544	34 (15–54)	3.28 (2.03–5.29)	3.18 (2.08–4.84)
Excluding CD grade 3–5 complications	484	28 (6–51)	–	2.76 (1.65–4.66)
Propensity score regression	423	31 (8–54)	2.07 (1.14–3.77)	1.88 (1.04–3.41)
Propensity score matched	116	34 (3–64)	2.91 (1.36–6.20)	2.38 (0.99–5.73)
