Crude and adjusted odds ratios for 30-day mortality

	OR, crude (95% CI)	p for crude OR	OR, adjusted (95% CI)	p for adjusted OR
RDW a	1.32 (1.17–1.50)	< .001	1.32 (1.16–1.50)	< .001
CFS b	1.47 (1.22–1.78)	< .001	1.43 (1.18–1.73)	< .001
Age c	1.03 (1.00–1.07)	.076	1.04 (1.00–1.08)	.082
Female	0.73 (0.47–1.14)	.169	0.67 (0.42–1.05)	.083

Binary logistic regression was used for the analysis. RDW class, CFS, age, and sex were included in the analysis for adjusted odds ratios
