| Female sex | 365 (59) | 329 (55) |
| No. of chronic conditions (mean, SD)a | 4.1 (2.1) | 4.8 (2.3) |
| ACG score (median, IQR)b | 0.29 (0.22–0.42) | 0.25 (0.18–0.39) |
| Number of medications at baseline (mean, SD) | 6.6 (3.3) | 7.1 (3.2) |

p value < 0.05 for difference between groups for age, number of chronic conditions, ACG score, and number of medications (overall and symptom-focused) at baseline
a From a list of 27 chronic conditions
b ACG scores for some subjects are below the enrollment threshold because these scores shifted between the time these subjects were identified as eligible to participate to the time they were enrolled
