Decision curve analysis for gestational diabetes mellitus. Solid black line = net benefit when no one is at risk for gestational diabetes mellitus (GDM); grey line = net benefit when all are at risk for GDM. The y-axis measures the net benefit. The red line represents the nomogram. The decision curve showed that if the threshold probability is between 0.05–0.78, using the nomogram in the current study to predict GDM adds more benefit than the intervention-all-patients scheme or the intervention-none scheme
