Baseline Characteristics of Participants and Matched Controls
| Characteristic | Participants | Matched Controls | Absolute Standardized Difference* |
|---|---|---|---|
| N | 237 | 400 | n/a |
| Age, mean (SD), y | 43.3 (9.6) | 43.7 (7.5) | 0.04 |
| % Female | 90% | 90% | 0 (Exact matching) |
| % White/Caucasian | 77% | 77% | 0 (Exact matching) |
| Baseline health spend, mean (SD), $ | $10,052 ($15,760) | $9367 ($13,338) | 0.05 |
| HCC risk score, mean (SD) | 0.81 (2.1) | 0.76 (1.5) | 0.03 |
| SVI, mean (SD) | 0.4 (0.3) | 0.4 (0.2) | 0.02 |
*An absolute standardized difference between participants and matched controls of less than 0.10 is a strong indication of balance and suggests no selection bias.
