CYYR1 and bronchopulmonary dysplasia: A nomogram was developed for BPD diagnosis using CYYR1, GALNT14, and OLAH, as illustrated in Figure 8A. The calibration curve demonstrated that the nomogram model had excellent predictive ability with minimal variation between observed and predicted risk, as indicated in Figure 8B. Furthermore, decision curve analysis indicated that the hub gene nomograms had a substantial net benefit in predicting BPD risk at a risk threshold of 0.1 to 1.0, as shown in Figure 8C.
