Gender differences in the relationship between the triglyceride-glucose index and serum Klotho concentrations among the middle-aged and elderly: a cross-sectional analysis

Table 4 Threshold effect analysis for the relationship between TyG index and serum Klotho concentrations in the female group

Model	Serum Klotho concentrations
Model	Adjusted β (95% CI)	P Value
Model I
The standard linear mode	-83.41 (-124.23, -42.60)	< 0.0001
Model II
Turning point (K)
TyG index < 9.4	-111.43 (-157.34, -65.52)	< 0.0001
TyG index > 9.4	119.09 (-39.66, 277.84)	0.1418
Log likelihood ratio test	0.009

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
BMI: Body mass index; PIR: Poverty income ratio; CHF: Congestive heart failure; CHD: Coronary heart disease; COPD: Chronic obstructive pulmonary disease; HDL-C: High-density lipoprotein cholesterol; LDL-C: Low-density lipoprotein cholesterol; eGFR: Estimated glomerular filtration rate
