Visceral adiposity index and risks of cardiovascular events and mortality in prevalent hemodialysis patients

Table 3 VAI, WC and WHtR in all participants analyzed by Cox proportional-hazards regression model with multivariate adjustments (with the stepwise forward likelihood ratio method)

Variables	Composite outcome		Cardiovascular outcome		All-cause mortality
	Adjusted HR (95% CI)^§	P	Adjusted HR (95% CI)^§	P	Adjusted HR (95% CI)^§	P
VAI (tertile 2 vs. tertile 1)	1.5 (1.07-2.08)	0.04	1.72 (1.13-2.63)	0.01	-	0.8
VAI (tertile 3 vs. tertile 1)	1.62 (1.22-2.32)	0.04	1.69 (1.11-2.6)	0.02	-	0.4
WC (every 10 cm increase)	-	0.4	-	0.3	-	0.1
WHtR (every 0.01 unit increase)	-	0.1	-	0.2	-	0.2
Taking VAI as a continuous variable
VAI (every 1 unit increase)	1.4 (1.23-2.25)	0.01	1.69 (1.3-2.2)	0.01	-	0.4
WC (every 10 cm increase)	-	0.4	-	0.3	-	0.1
WHtR (every 0.01 unit increase)	-	0.1	-	0.2	-	0.2
