Participants with potassium 3.5–4.5 g/day were reference group. Numbers are presented with percentages in parentheses in each potassium group. Odds ratios are given with 95% confidence interval in parentheses.

Model I: Adjusted for age, BMI.

Model II: Adjusted for Model I+alcohol intake, exercise, education, income, residential area, frequency of fruit intake, energy, and carbohydrate energy ratio.

Abbreviations: IR, insulin resistance; BMI, body mass index; OR, odds ratio; CI, confidence interval.
