Univariate analysis of disease-free survival (DFS) and overall survival (OS) using product-limit estimates.

Marker	Median DFS in months (95% CI)		log rank test p-value
Marker	negative / absent	positive / present	log rank test p-value
bcl-2	63.8 (49.3, 98.0)	70.2 (32.5, NE^*)	0.7403
p53	105.2 (56.6, NE)	55.8 (36.5, 77.0)	0.0485
Blood group antigen A	73.6 (47.2, NE)	67.3 (50.8, 107.0)	0.9207
Mucin	107.0 (70.2, NE)	41.5 (25.2, 73.6)	0.0005

Marker	Median OS in months (95% CI)		log rank test p-value
Marker	negative / absent	positive / present	log rank test p-value

bcl-2	79.0 (67.0, NE)	NE^* (52.4, NE)	0.2205
p53	109.4 (78.4, NE)	73.5 (52.4, 98.0)	0.0633
Blood group antigen A	98.4 (73.6, NE)	79.0 (65.6, 113.1)	0.7399
