Figure 3. Distribution of EFT values of GDM, PGDM and control groups (a) . ROC curves constructed with the multivariate logistic regression model. The AUC of EFT with other variables (FPG, 1hPG, 2hPG, HbA1c, AC and DVP) for the diagnosis of GDM (1.000) is larger than when using the individual factors of EFT (0.985), FPG (0.643), 1hPG (0.956), 2hPG (0.976), HbA1c (0.902), AC (0.696) and DVP (0.669) (b) . The AUC of EFT with other variables (HbA1c, AC and DVP) for the diagnosis of PGDM (1.000) is larger than when using the individual factors of EFT (0.999), HbA1c (0.934), AC (0.858) and DVP (0.814) (c) . 1hPG, 1 hour plasma glucose; 2hPG, 2 hour plasma glucose; AC, abdominal circumference; DVP, deepest vertical pocket; EFT, epicardial fat thickness; FPG, fasting plasma glucose; GDM, gestational diabetes mellitus; PGDM, pregestational diabetes mellitus.
