Mean Absolute Relative Difference by Glucose Strata in Hospitalized Patients With or Without Congestive Heart Failure

	Non-CHF		CHF
Glucose strata (mg/dL)	n	Median (IQR)	n	Median (IQR)	P value
<100	38	0.08 (0.02–0.21)	75	0.10 (0.06–0.26)	0.11
100–149	146	0.07 (0.02–0.14)	389	0.10 (0.04–0.18)	0.003
150–199	117	0.07 (0.03–0.14)	304	0.09 (0.04–0.16)	0.05
>200	91	0.05 (0.01–0.10)	160	0.07 (0.03–0.15)	0.02

Data are median (interquartile range [IQR]) values. Differences between groups were determined using Wilcoxon's rank-sum test.

CHF, congestive heart failure; MARD, mean absolute relative difference.
