Development and performance of radiomic nomogram. a Radiomic nomogram developed to predict COPD. b Calibration curve between the predicted and actual incidences of COPD. c Decision curve analysis compares the net benefits of four scenarios in predicting the risk of COPD: Combined model (red line), Clinical model (blue line), All (green line, refers to the assumption that all patients have COPD) and None (horizontal solid black line, represents the assumption that no patient has COPD).
