Model | AUC | P value | NRI | P value |
Deep learning (DL) | 0.81 | Reference | Reference | Reference |
Diameter stenosis | 0.62 | 0.04 | 0.60 | 0.10 |
Area stenosis | 0.58 | 0.05 | 0.75 | 0.03 |
QFR | 0.67 | 0.13 | 0.95 | 0.01 |
P values for AUC analysis represent comparison of the DL model (reference) with classification based on each angiographic parameter. Continuous NRI was used along with its p value.
AUC, area under the curve; QFR, quantitative flow ratio.
