Multivariable logistic regression analysis for the detection of the factors related to the history of stomach cancer

95% CI for OR: 95% confidence interval for the odds ratio. E24UNA_K: a continuous variable of the estimated 24-hr urine sodium excretion in 100 mEq/day unit, calculated with the equation created in this study. E24UNA_K2: a group of E24UNA_K stratified with a criterion of 240 mEq/day. E24UNA_K2 (high): participants with ≥241 mEq/day of E24UNA_K. E24UNA_T: a continuous variable of estimated 24-hr urine sodium in 100 mEq/day unit, calculated with the equation created by Tanaka et al. E24UNA_T2 (high): participants with ≥261 mEq/day, as calculated by using the E24UNA_T model. Model 1: logistic regression for the presence of stomach cancer adjusted for age and sex. Model 2: adjusted for age, sex, and smoking and drinking habits. Model 3: adjusted for age, sex, smoking and drinking habits, grade of household income, marital status, employment status, grade of education-year, history of ischemic heart disease, colon cancer, lung cancer, presence of diabetes mellitus, hypertension, and chronic kidney disease at the time of the survey.
