Figure 3.

The mortality risk prediction model for patients with polymyositis/dermatomyositis-associated interstitial lung disease is presented as a nomogram (A). Discrimination was evaluated using the area under the receiver operating characteristic curves for both the prediction model and other indicators in the development cohort (B) and the internal validation cohort (C). HRCT, high-resolution CT; MDA5, melanoma differentiation-associated gene 5; NSIP, non-specific interstitial pneumonia; OP, organising pneumonia; UIP, usual interstitial pneumonia.
