Relative risk and incidence ratio of 30-day hospital readmission between patients with above basic versus basic/below basic levels of health literacy

Health literacy estimates (above basic vs basic/below basic)	Model 1: no covariates	Model 2: adjusting for age and gender only	Model 3: adjusting for age, gender and clinical risk factors
Relative risk of having a 30-day readmission (95% CI), p value	0.816 (0.729 to 0.914), <0.0001	0.814 (0.727 to 0.911), <0.0001	0.882 (0.788 to 0.987), 0.029
Incidence rate ratio of 30-day readmissions (95% CI), p value	0.768 (0.676 to 0.872), <0.0001	0.766 (0.674 to 0.871), <0.0001	0.837 (0.737 to 0.951), 0.006
