Comparison of different models for discrimination of ischaemia (FFR ≤0.80; N = 484 vessels)
| Model | Wald test, P-value | AUC (95% CI) |
|---|---|---|
| Model 1: Stenosis >50% | Comparison with no effect, <0.001 | 0.71 (0.67–0.76) |
| Model 2: Stenosis >50% + LD-NCP ≥30 mm3 | Comparison with Model 1, <0.001 | 0.79 (0.74–0.84) |
| Model 3: Stenosis >50% + LD-NCP ≥30 mm3 + FFRCT ≤0.80 | Comparison with Model 2, <0.001 | 0.90 (0.87–0.93) |
FFR, fractional flow reserve; AUC, area under the receiver-operating characteristics curve; CI, confidence interval; LD-NCP, low-density non-calcified plaque; FFRCT, fractional flow reserve derived from coronary computed tomography angiography.
