  1. Linear regression analysis, where electrolyte levels is used as the dependent variable, FPG, 2hPG, HbA1c are the independent variables, and gender, age, BMI, SBP, DBP, TG, HDL and eGFR levels are the co-variables, using the Enter method.
  2. Abbreviations: FPG Fasting plasma glucose, 2hPG 2-hour post-load plasma glucose, HbA1c Glycosylated hemoglobin, Na Sodium, K Potassium, Ca Calcium, Mg Magnesium.
