Pairwise effects of method on interregional correlation.

(A) Marginal correlation. (B) Absolute change in marginal correlation. Upper triangular matrix: significance level of a pairwise effect of method. Significant -values at a threshold of corrected are emphasized in bold. Lower triangular matrix: direction of effect; n.s.: nonsignificant. Note that, since changes are usually negative, a larger change means a change that is smaller in amplitude.
