A The DCA decision curve of the original model and the simple model. The transverse solid line represented the probability of risk that none of objects suffered from GDM, the oblique solid line represents the probability of risk that object suffer from GDM, and the y-axis assessed the net benefit. The DCA curve illustrated similar net profit rates for the original model (red line) and the simple model (blue line) within the threshold range of 0.1 to 0.8. Notably, the application of the simple model incurred only a marginal reduction in the net profit rate. B The clinical impact curve showed the number of objects diagnosed GDM by the simple model and the number of objects with actual GDM at each threshold probability. Combining application convenience and clinical significance, the simple model had more practical application values compared to the original model. Note: decision curve analysis, DCA; GDM, gestational diabetes mellitus
