Health-related quality-of-life domain scores in those with and without claudication.
| Median (5–95 percentile) | |||

| Role limitation (physical) | 25.0 (0–100.0) | 100.0 (0–100.0) | ≤0.001 |
| Role limitation (emotional) | 100.0 (0–100.0) | 100.0 (0–100.0) | 0.007 |
| Social functioning | 88.9 (11.0–100.0) | 100.0 (33.3–100.0) | 0.083 |

| Pain | 66.7 (15.0–78.0) | 88.9 (22.0–100.0) | 0.009 |
| General health perception | 57.0 (22.0–100.0) | 72.0 (25.0–97.0) | 0.001 |
Missing data arose from missing claudication status data or where those with claudication data were missing health-related quality-of-life data. IC = intermittent claudication.
