Data are expressed as hazard ratio, 95% confidence interval, P value. Besides unadjusted overall estimates, the other risk estimates were calculated after adjusting for age, gender, smoking, drinking, family cancer history, body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, TNM stage, tumor size, Lauren’s classification, number of lymph node metastasis and tumor embolus by removing the characteristic itself in stratified analysis
