The results of two-piecewise linear regression model between Waist-BMI Ratio and cause-specific mortality.

	Overall mortality	Cardiovascular mortality
Cutoff value	3.72	3.66
<Cut-off value	1.16 (0.93, 1.44) 0.188	1.00 (0.58, 1.73) 0.999
≥Cut-off value	3.22 (2.43, 4.26) <0.001	3.07 (1.71, 5.52) <0.001
P for log likelihood ratio test	<0.001	0.008

Data are hazard ratios (HRs), 95% confidence intervals (95% CIs), and P-value.

The two-piecewise linear regression model were adjusted for age, gender, race, smoking, SBP, HDL-cholesterol, total cholesterol, eGFR, comorbidities (hypertension, diabetes, and cardiovascular disease), and medicine use (antihypertensive drugs, hypoglycemic agents, lipid-lowering drugs, and antiplatelet drugs).
