Note: Listed are the mean and standard deviation of intersession, intrasession, and multiscan ICCs for all, significant, nonsignificant, positive significant, or negative significant correlations for each seed set. The last column of each table indicates the P-value for the comparison of inter- and intrasession ICCs. Significant P-values (less than 0.01, corrected for 5 comparisons for each seed set) are marked in italics.
