Survival analysis of histopathologic prognostic factors in pancreatobiliary resections (n = 67)

			p-value
	HR	95% CI	Univariate	Multivariable
Pancreatic tumour origin (pancreatic vs non-pancreatic)	2.3	1.3–4.0	0.004
pT stage (pT3 or pT4 vs pT1 or pT2)	2.0	0.9–4.2	0.073
Resection margin involvement (R1 vs R0)	1.7	1.0–2.8	0.052
Lymph node involvement (N1 vs N0)	3.0	1.6–5.4	< 0.001	0.007
Poor differentiation (yes vs no)	1.6	0.9–2.6	0.094
Vessel involvement (yes vs no)	3.1	1.8–5.3	< 0.001	0.035
Perineural infiltration (yes vs no)	2.8	1.4–5.5	0.003
Tumour size (continuous, measured in cm)	1.7	1.3–2.1	< 0.001	< 0.001

HR, hazard ratio. HR > 1 indicates increased probability of death

CI, confidence interval
