Stepwise multivariate regression models for overall survival, progression-free survival, and freedom from distant progression

Outcome	Hazard ratio	P value
Overall survival
Baseline CA19-9	1.37	.004
Age	1.05	.030
Sex (F vs M)	0.40	.034
Progression-free survival
Baseline CA19-9	1.38	.001
Sex (F vs M)	0.50	.050
Freedom from distant progression
Baseline CA19-9	1.40	.006
Sex	0.265	.007

Abbreviation: CA19-9 = carbohydrate antigen 19-9.

All variables were considered as continuous variables unless otherwise noted. No models containing multiple variables for freedom from local progression were identified.
