Figure 3. The correlation between the mean DC value of left ITG and the duration (A) and MMSE (B). In the Alzheimer's disease group, the mean DC value of left ITG showed a negative correlation with duration (r2=0.968, P<0.001). The mean DC value of the left ITG was positively correlated with MMSE (r2=0.953, P<0.001). Abbreviations: DC, Degree centrality; MCI, mild cognitive impairment; ITG, inferior temporal gyrus; L, left; MMSE, Mini-Mental State Examination.
