| Lack of health insurance | 6 (1.7%) | 3 (1.2%) | 3 (2.6%) |
| DSST score (cognition) | 28.9 (12.0) | 29.5 (12.4) | 27.8 (11.0) |
| Confidence in filling out medical forms (health literacy), mean (SD) | 3.8 (1.2) | 3.9 (1.2) | 3.7 (1.2) |

CATI = computer-assisted telephone interview; CHD = coronary heart disease; DSST = digit symbol substitution test (score based on the count of numbers matched to symbols; higher scores indicate better cognition); HF = heart failure characteristics; HFrEF = heart failure with reduced ejection fraction.
Frequency (%) and mean (SD) are presented as appropriate. Confidence in filling out medical forms is scored from 1 to 5, wherein 5 is most confident and 1 is least confident.
