Figure 4. Partial correlation was applied to examine the relationships between MSE and MOCA in the entire sample, controlled for age, education, head motion, and GM. The entropy showed significant positive correlations in the hippocampus, IPL, and SFG (A), and negative correlation with the MOG (C). While no significant correlation was found between MOCA and entropy in the PCG (A), cuneus (B), and MFG (C). Note: PCG, precentral gyrus; IPL, intraparietal lobe; SFG, superior frontal gyrus; MFG, middle frontal gyrus; MOG, middle occipital gyrus; GM, gray matter. *, p<.05; **, p<.01; ***, p<.001.
