Association of quartiles of baseline Red Cell Distribution Width with All-cause Mortality in Patients with Peripheral Artery Disease

Quartiles	N	Deaths	HR (95% CI)	P value
1	3008	779 (25.9%)	Referent	/
2	3378	891 (26.4%)	1.06 (0.95-1.18)	0.94
3	3273	975 (29.8%)	1.20 (1.09-1.34)	0.0005
4	3380	1394 (41.2%)	1.66 (1.49-1.85)	<0.0001

^*Adjustments as in model 2 in Table 2.

Q1 = red cell distribution width <12.8%; Q2 = red cell distribution width 12.8%–13.5%; Q3 = red cell distribution width 13.5% –14.5%; Q4 = red cell distribution width > 14.5%
