Threshold analysis for the relationship between body mass index (BMI) and incident of elevated liver stiffness

Models	Adjusted OR (95% CI)a	P
Model I
One line slope	1.23 (1.16, 1.30)	< 0.0001
Model II
Turning Point of BMI (K point)	23.05
< K slope 1	0.84 (0.71, 0.98)	0.027
> K slope2	1.32 (1.24, 1.41)	< 0.0001
LRT test	< 0.001b

^aAdjusted for age, sex, mean arterial pressure, history of coronary heart disease, history of Diabetes, history of Hypertension, alanine transaminase (ALT), fasting blood–glucose (FBG), Creatinine, total triglyceride (TG), high-density lipoprotein (HDL)

^bMeans that Model II is significant different from Model I

LRT test means Logarithmic likelihood ratio test
