The result of two-piecewise linear regression model.

Incident diabetes:	HR, 95%CI	P
Fitting model by standard Cox regression	1.011 (1.010, 1.012)	< 0.001
Fitting model by two-piecewise Cox regression
Inflection points of TyG-BMI	231.66
< 231.66	1.017 (1.014, 1.019)	< 0.001
≥231.66	1.007 (1.005, 1.009)	< 0.001
P-for log-likelihood ratio test		< 0.001

We adjusted age, sex, SBP, DBP ALT, AST, BUN, LDL-C, HDL-c, family history of diabetes, drinking status, and smoking status.
