Table 2.

Adjusted HRs (95% CI) of all-cause and cardiovascular mortality across quartiles of GNRI.

	Harrell’s c-index	Quartiles of GNRI				P for trend
		Q1 (≤89.3) (n = 1080)	Q2 (89.4 to 94.9) (n = 981)	Q3 (95.0 to 98.7) (n = 1029)	Q4 (≥98.8) (n = 1015)
All-cause mortality
Model 1	0.726 (0.701, 0.750)	2.24 (1.60, 3.13)	1.27 (0.91, 1.78)	0.94 (0.66, 1.34)	1 [reference]	<0.001
Model 2	0.749 (0.725, 0.772)	2.21 (1.61, 3.03)	1.19 (0.85, 1.66)	0.95 (0.67, 1.34)	1 [reference]	<0.001
Cardiovascular mortality
Model 1	0.708 (0.668, 0.749)	1.60 (0.95, 2.70)	0.93 (0.52, 1.64)	1.20 (0.72, 1.98)	1 [reference]	0.19
Model 2	0.747 (0.710, 0.783)	1.61 (0.98, 2.62)	0.87 (0.50, 1.54)	1.20 (0.73, 1.98)	1 [reference]	0.19

Data are expressed as HR (95% CI).

Model 1 was adjusted for age and gender.

Model 2 was adjusted for age, gender, dialysis vintage, and comorbidity (history of diabetes mellitus and cardiovascular diseases).

A P-value < 0.05 was considered statistically significant.

Abbreviations: CI, confidence interval; GNRI, geriatric nutritional risk index; HR, hazards ratio; Q, quartile.
