The results of two-piecewise linear regression model for BRI and all-cause mortality and cardiovascular mortality

	All-cause mortality			Cardiovascular mortality
	HR	95 % CI	P-value	HR	95 % CI	P value
Cutoff value	4·99			3·60
<Cut-off value	0·67	0·60, 0·75	<0·001	0·32	0·18, 0·56	<0·001
≥Cut-off value	1·11	1·05, 1·16	<0·001	1·08	0·99, 1·19	0·0768
P for log likelihood ratio test	<0·001			<0·001

Data were showed by HR, 95 % CI and P value.

The two-piecewise linear regression model was adjusted for age, gender, race, smoking, SBP, DBP, eGFR, HDL, TC, CVD, hypertension, diabetes, lipid-lowering drugs, antihypertensive drugs, hypoglycaemic agents and antiplatelet drugs.
