From: Risk prediction models of gestational diabetes mellitus before 16 gestational weeks
ROC curves and DCA. A Comparison between the basic model and the previous published model. B DCA of the basic model and the previous published model. C Comparison between the extended model and the previous published model. D DCA of the extended model and the previous published model. The horizontal line represented no cases will experience GDM; while the oblique line represents all cases will experience GDM. In the DCA, the area between the “black horizontal line” and “gray slope line” of the model curve meant the clinical validity of the model. The colorful lines represent the clinical net benefits according to the threshold probabilities. ROC, receiver operating characteristic curves; DCA, decision curve analysis; GDM, gestational diabetes mellitus
