Fig. 3

Analysis of the relationship between dietary potassium intake and the risk of gallstones, stratified by basic demographic factors, lifestyle factors, and dietary elements. For each stratification, the analysis was adjusted for all other variables, excluding the stratification component itself. The variables included in the adjustments were age, gender, race, educational level, marital status, PIR, body mass index (BMI), alcohol consumption, smoking status, diabetes, hypertension, dietary supplement use, asthma, cancer, physical activity, total calorie intake, total sugar, total fat, total carbohydrate, total protein, total water, total cholesterol, calcium intake, iron intake, zinc intake, copper intake, sodium intake, and selenium intake. This approach ensures that the effects of potassium intake on gallstone risk are examined within distinct subgroups while controlling for potential confounding factors
