Fig. 5From: The association between diabetes mellitus and reduction in myocardial glucose uptake: a population-based 18F-FDG PET/CT studyROC curve analysis was used to assess the efficacy of using visual grading of myocardial FDG uptake to predict diabetes. When FDG uptake ≤ Grade 1, the sensitivity of predicting diabetes was 84%, the specificity was 58.43%, AUC = 0.745, and 95% confidence interval was 0.677 ~ 0.805 (z = 5.859, P < 0.001)Back to article page
