Fig 2
Sensitivity analysis of adjusted OR (95% CI) for hypertension by sodium and potassium intake across four multivariate models.
Multivariable logistic regression models (Model 1 to Model 4) were used with progressively adjusted covariates. Model 1: unadjusted; Model 2: adjusted for age and gender; Model 3: additionally adjusted for race/ethnicity, education level, and marital status; Model 4: further adjusted for smoking status, alcohol consumption, and physical activity.
