Table 2. A comparison of radiologists and cohorts.
| PPV | NPV | Sensitivity | Specificity | AUC | Accuracy | |
|---|---|---|---|---|---|---|
| R2 without SA diameter | 64.70% | 61.60% | 54.70% | 70.90% | 0.626a,b | 62.70% |
| R2 with SA diameter | 62.70% | 66.10% | 68.20% | 60.40% | 0.643a,c | 64.30% |
| R3 without SA diameter | 65.50% | 68.50% | 69.80% | 64.10% | 0.671b,d | 67.10% |
| R3 with SA diameter | 64.60% | 69.40% | 72.30% | 61.30% | 0.670c,d | 66.90% |
| Deep transfer learning method | 95.20% | 95.30% | 95.30% | 95.20% | 0.994 | 95.70% |
Note: Compared to the radiologist’s AUC: c, P<0.05; a, b, and d, P>0.05. R2, radiologist 2 with 5-year experience; R3, radiologist 3 with 10-year experience; SA, short axial; PPV, positive predictive value; NPV, negative predictive value; AUC, area under the receiver operating characteristic curve.
