Multivariate Cox regression analysis.

Clinicopathologic features	HR	95% CI	P value
Location (vs. UTG)	0.282	0.146–0.544	P<0.001*
Invasion depth (vs. T1–T2)	0.955	0.382–2.389	P=0.922
TNM stage (vs. I–II)	2.726	1.052–7.066	P=0.039*
USP33 expression (vs. low)	0.432	0.223–0.839	P=0.013*

UTG – upper third gastric; USP33 – ubiquitin specific peptidase 33.
