| Race/ethnicity | 0.92 (0.66–1.27) | 0.597 | 1.32 (1.01–1.73) | 0.038 |
| Rural/urban residence | 1.00 (0.76–1.31) | 0.906 | 1.45 (1.15–1.82) | 0.002 |

| Composite | 0.124§ | 0.001§ | ||
| Moderately vulnerable | 0.87 (0.69–1.09) | 1.42 (1.16–1.73) | ||
| Vulnerable | 1.37 (0.85–2.19) | 1.57 (1.12–2.22) | ||
Adjusted for mammogram-level study site, age (5-year bands), breast density, and time since previous mammogram.
“Nonvulnerable” is taken to be the referent group.
Based on a likelihood-ratio test which include/excludes single-vulnerability index.
P value for overall composite index, jointly assessing 2 vulnerability levels vs. referent nonvulnerable group.
