The relationship between TyG index and serum Klotho concentrations in the female group. Solid line in the middle represents smooth curve fitting between variables. The dotted line on both sides represents a 95% confidence interval (CI) for the fit. The bottom black and white strip shows the population density according to TyG index. All models were adjusted for age, race, PIR, BMI, waist circumference, education, smoking, alcohol consumption, HDL-C, LDL-C, eGFR, cancer, stroke, CHF, CHD, angina, heart attack, COPD, hypoglycemic drugs or insulin use, lipid-lowering drug use, diabetes, and hypertension
