Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of high-resolution computed tomography fibrotic scores (CTfib) for identifying usual interstitial pneumonia in patients with idiopathic interstitial pneumonia
| Radiographic feature | Sensitivity % | Specificity % | PPV % | NPV % |
| Mean CTfib≥2 for all lobes | 46 | 93 | 93 | 47 |
| Mean CTfib≥2 for at least one lobe | 90 | 86 | 92 | 69 |
