Table 3. Adjusted means and standard errors of HoMA-IR, fasting insulin, and QUICKI according to 24-h estimated urinary sodium-potassium ratio.

Q, quartile; 24HUNa-K Ratio, 24-h urinary Na-K ratio; HoMA-IR, homeostasis model assessment of insulin resistance; QUICKI, quantitative insulin sensitivity check index.

¹⁾P-value and P-trend were calculated by applying general linear model.

²⁾Adjusted for age (continuous) and sex (men, women)

³⁾Lsmean ± SE

⁴⁾Adjusted for age (continuous), sex (men, women), body mass index (continuous, kg/m²), cigarette smoking status (current smoker, non/past smoker), alcohol consumption status (current drinker, non/past drinker), regular exercise status (yes, no), and recruitment area (Ansan, Ansung)

⁵⁾Tukey's multiple comparison test, P < 0.05
