This table depicts functional connectivity and reliability results of each connection at different spinal segments. r represents the mean Pearson correlation across participants, t and p represent the t-value and two-tailed family-wise-error corrected p-value from a permutation test (against 0), respectively. ICC (95% CI) represents ICC(2,1) values and 95% bootstrapped confidence intervals.
