Coefficients, moderated t-statistics and corresponding p-values for testing all possible contrasts were calculated using Empirical Bayesian methods.
The contrast was calculated using Eq. (1).
Planned contrasts were calculated using the 'estimate' command in SAS for the 'glimmix' procedure.
Contrasts were calculated using the method of phylogenetically independent contrasts [ 92].
For each contrast moderated t-statistics were calculated using an empirical Bayes method [ 53].
Predetermined condition effects at each voxel were calculated using a t-statistic, producing a statistical image for the contrasts of 2-Back versus 0-Back (N-Back).
The contrasts of interest were calculated using the contrasts.fit function and their significance (statistical analysis) was determined using the eBayes function in limma.
Contrast transfer function parameters were calculated using CTFFIND3 (Mindell and Grigorieff, 2003).
Regression coefficients were calculated using the Contrast program in PHYLIP, version 3.69555.
Odds ratios (ORs) and 95% CIs were calculated using the contrast statement in SAS 9.2.
