Table 4.

Significant clusters for psychophysiological interaction analyses with drinks per drinking day as a covariate using the Alcohol > Beverage contrast, across groups. Z-statistic maps were thresholded using cluster-corrected statistics with a height-threshold of Z > 2.3 and cluster-forming threshold of p < 0.05. All coordinates are in MNI space.
