Fig. 2: Cox proportional hazard model for clinical factors.

A Forest plot for clinical factors. The characteristic used for comparison was labeled “Reference”. A black box denotes the mean hazard ratio for each comparison to the reference. Error bars on forest plots represent the 95% confidence interval for each hazard ratio. Significant P values were shown in bold. Kaplan–Meier curves were shown for B Lauren classification, C differentiation, and D peritoneal metastasis. Log-rank test was used to determine significance.
