This table depicts functional connectivity and reliability results of each connection across seven denoising pipelines. r represents the mean Pearson correlation across participants, and t and p represent the t-value and two-tailed FWE-corrected (for seven tests) p-value from a permutation test (against 0), respectively. ICC(95% CI) represents ICC(2,1) values and 95% bootstrapped confidence intervals.
