Abbreviations: ADAS Cog, (Mod), modified version of the Alzheimer's Disease Assessment Scale-cognitive subscale; Aud, auditory network; iFC, intrinsic functional connectivity; lAtt, left attention network; pdDMN, posterior-dorsal default mode network; pvDMN, posterior-ventral default mode network; rAtt, right attention network; Sens, sensorimotor network; Vis, visual network.
NOTE. No partial Pearson correlation coefficients (r), controlling for age and sex, were significant following correction for multiple comparisons (corrected a ≤ .006).
∗
Significant/marginally significant correlations at P ≤ .05, before multiple comparison correction.
