Aortic OCT analyses at week 12, subdivided by balloon injury status
| No balloon injury (n=2) | Balloon injury (n=4) | Difference between means (95% CI) | p value | |
|---|---|---|---|---|
| Plaque volume indexed (mm3/mm) (mean±SEM) | 1.96±0.05 | 3.71±0.08 | 1.75 (1.56 to 1.93) | <0.0001 |
| Modified lumen stenosis (%±SEM) | 22.5±0.7 | 42.8±0.7 | 20.3 (18.4 to 22.2) | <0.0001 |
| Mean maximal IM thickness (mm±SEM) | 0.28±0.01 | 0.56±0.01 | 0.28 (0.25 to 0.31) | <0.0001 |
| Plaque eccentricity (mean±SEM) | 0.44±0.02 | 0.49±0.01 | 0.05 (0.02 to 0.08) | 0.001 |
| Lumen eccentricity (mean±SEM) | 0.09±0.01 | 0.18±0.01 | 0.09 (0.07 to 0.10) | <0.0001 |
