Hyperintensities of middle frontal gyrus in patients with diabetic optic neuropathy: a dynamic amplitude of low-frequency fluctuation study


Figure 3. ROC curve analysis of the mean dALFF values for altered brain regions. (A) DON>HCs, the area under the ROC curve was 0.997 (P < 0.0001; 95% CI: 0.985–1.000) for MFG_R. (B) DON<HCs, the area under the ROC curve was 0.858 (P < 0.0001; 95% CI: 0.737–0.979) for PreC_R. Abbreviations: ROC, receiver operating characteristic; dALFF, dynamic amplitude of low-frequency fluctuation; DON, diabetic optic neuropathy; HCs, healthy controls; AUC, area under the curve; R, right; MFG, middle frontal gyrus; PreC, precuneus.
