Brain hemodynamic changes in amnestic mild cognitive impairment measured by pulsed arterial spin labeling
Figure 2. Correlation between the MMSE and mean CBF of each cluster in each group. The mean CBFs in right inferior temporal gyrus (Cluster 2), precuneus, and postcentral gyrus (Cluster 3) were positively correlated with MMSE in the aMCI but not NC group. β: Regression parameter; Solid line: line of best fit; Blue shadow: 95% confidence interval; Dashed line: 95% prediction interval. *. Correlation is significant at the 0.05 level (two-tailed). **. Correlation is significant at the 0.01 level (two-tailed).
