The Effect of Numeracy on 30-Day Readmissions among those hospitalized for Acute Decompensated Heart Failure (ADHF) in the Vanderbilt Inpatient Cohort Study (VICS)

Numeracy	Model 1			Model 2			Model 3			Model 4			Model 5
Numeracy	RR	95% CI	P-Value	RR	95% CI	P-Value	RR	95% CI	P-Value	RR	95% CI	P-Value	RR	95% CI	P-Value
Numeracy Score (per 2 point change)	1.02	0.86 – 1.23	0.79	1.09	0.89 – 1.33	0.39	1.04	0.83 – 1.29	0.75	1.06	0.85 – 1.33	0.57	1.04	0.83 – 1.30	0.72

Poisson Model Estimates

Model 1 adjusts for numeracy alone

Model 2 adjusts for the Model 1 variable and adjusts for health literacy and cognitive impairment variables

Model 3 adjusts for the Model 2 variables and demographics

Model 4 adjusts for Model 3 variables and clinical and diagnostic characteristics

Model 5 adjusts for Model 4 variables and hospitalization characteristics
