TABLE 3.
Partial Pearson r coefficients (first row of each cell), p-values (second row), and 95% CI (third row) of the correlations between individual MMSE scores and EEG features (and reaction times), controlled for age as a function of task (averaged across tasks, resting state, detection level 1, and detection level 2), and the difference between correlation coefficients and Cis, the partial correlations, and the unadjusted correlations, as calculated by the bias-corrected and accelerated (BCa) bootstrap method.
