The results of two-piecewise linear regression model between the TC/HDL-C ratio and all-cause mortality and cardiovascular mortality.

	All-cause mortalityHR (95% CI) P-value	Cardiovascular mortalityHR (95% CI) P-value
Cutoff value	3.66	4.22
<Cutoff value	0.84 (0.75, 0.93) 0.001	0.91 (0.75, 1.10) 0.331
≥Cutoff value	1.13 (1.09, 1.17) <0.001	1.13 (1.02, 1.25) 0.015
P for log likelihood ratio test	<0.001	0.076

HR, hazard ratio; CI, confidence interval.

The two-piecewise linear regression model was adjusted for age, gender, race, smoking, body mass index, systolic blood pressure, estimated glomerular filtration rate, total cholesterol, comorbidities (diabetes and hypertension), and medicine use (antihypertensive drugs, hypoglycemic agents, and lipid-lowering drugs).
