Table 6

Multivariate analyses of overall survival in gastric cancer patients whose tumor size was larger than 5 cm (Cox’s regression model).

Variable	HR	95% CI	value
OS in gastric cancer patients whose tumor size was larger than 5 cm
Borrmann type	1.644	1.039–2.600	0.034
Tumor location	1.116	0.858–1.451	0.414
Pathological T staging	4.761	2.836–9.487	<0.001
Postoperative chemotherapy	0.489	0.281–0.851	0.011

OS, overall survival; HR, hazard ratio; CI, confidence interval.
