Optimized Multiscale Entropy Model Based on Resting-State fMRI for Appraising Cognitive Performance in Healthy Elderly

Figure 5

Plot optimization effects indicated by ROC curves and AUC values in a single brain region. (a)–(c) ROC curves of STG.R with, 0.50, and 0.55, respectively, where the character of all ROC curves beyond the reference lines indicates STG.R to be a functional biomarker. (d)–(f) ROC curves of PoCG.R with , 0.50, and 0.55, respectively, where ROC curves around the reference lines suggest that PoCG.R was not a functional biomarker. (g) AUC values of STG.R. (h) AUC values of PoCG.R.
