Comparison (n = 85) of baseline features that develop a new surface disruption at follow-up versus lesions whose surface remains intact
| Univariate Regression | Independent t Test or Fisher Exact Test | ||||
|---|---|---|---|---|---|
| OR (95% CI) | AUC (95% CI) | Present (n = 9) | Absent (n = 76) | P Value | |
| Minimal lumen area (mm2) | 3.7 per 5-mm2 decrease (1.6–8.7) | 0.87 (0.77–0.97) | 8.9 ± 4.5 | 20.3 ± 10.5 | <.001 |
| Percentage wall volume | 2.6 per 5% increase (1.5–4.6) | 0.85 (0.71–0.98) | 62.5 ± 8.9 | 50.6 ± 7.2 | <.001 |
| Percentage LRNC volume | 2.6 per 5% increase (1.5–4.4) | 0.95 (0.90–1.00) | 16.2 ± 11.3 | 1.6 ± 4.4 | .005 |
| Prevalence of LRNC (%)a | 0.86 (0.77–0.94) | 100 | 28.9 | <.001 | |
| Prevalence of IPH (%) | 12.3 for presence of IPH (2.7–56.8) | 0.73 (0.53–0.94) | 55.6 | 9.2 | .55 |
a OR (95% CI) could not be calculated because 100% of lesions with a new surface disruption had an LRNC at baseline.
