Error bars indicate 95% confidence intervals of Pearson’s correlation coefficient. A statistical comparison was performed with the CU group. Pearson’s r (95% confidence interval) = 0.5873 (0.5628 to 0.6108), 0.6396 (0.5945 to 0.6847), 0.6735 (0.6138 to 0.7255), 0.7824 (0.6697 to 0.8598), and 0.6548 (0.5489 to 0.7400), for CU, MCI, AD, FTD, and DLB, respectively. Exact p values: CU versus MCI, p = 1.5 × 10−9; CU versus AD, p < 1 × 10−15; CU versus FTD, p < 1 × 10−15; CU versus DLB, p < 1 × 10−15, *** p < 0.001. *** p < 0.001, two-sided z test after Fisher’s r to z transformation.
