Predictive value of estimated pulse wave velocity for cardiovascular and all-cause mortality in individuals with obesity

Table 3 The results of two-piecewise linear regression model for ePWV and the risk of all-cause and CVD mortality in obese participants

Outcome	Inflection-point of ePWV (m/s)	HR	95% CI	P-value
All-cause Mortality
	< 6.7	0.5	0.1–2.0	0.314
	6.7–8.7	3.2	1.9–5.7	< 0.001
	≥ 8.7	1.3	1.2–1.6	< 0.001
CVD Mortality	< 7.2	0.5	0.1–2.0	0.245
	7.2–8.5	16.1	2.0–126.8	0.008
	≥ 8.5	1.3	1.1–1.6	< 0.001

HRs have been fully adjusted for confounders, which are the same as the variables adjusted for Model 2 in Table2 (Model 2* for all-cause mortality, Model 2 † for CVD mortality, respectively)
