Relationship between TyG and initial episode of PDRP.

	TyG ≥ 8.39 (vs. TyG < 8.39)		TyG (per unit increase)
	HR (95% CI)	P-value	HR (95% CI)	P-value
Unadjusted	1.610 (1.040–2.491)	0.033	1.733 (1.198–2.508)	0.004
Model 1	1.609 (1.035–2.503)	0.035	1.754 (1.197–2.571)	0.004
Model 2	1.689 (1.083–2.635)	0.021	2.015 (1.335–3.041)	0.001
Model 3	1.789 (1.145–2.795)	0.011	2.158 (1.427–3.261)	<0.001

TyG: triglycerides-glucose index; HR: hazard ratio; 95% CI: 95% confidence interval.

Model 1: age, sex, BMI.

Model 2: Model 1 plus history of diabetes, and history of CVD.

Model 3: Model 2 plus serum creatinine, serum uric acid, corrected calcium, serum phosphorus, and serum albumin.
