Significant results of the exploratory follow-up analyses examining the correlation between alcoholism severity and priming-related alcohol cue reactivity were not observed at a voxel height threshold of Z>2.3 (cluster-corrected). Due to the limited power afforded by the smaller sample size, the threshold was reduced to Z>1.96, which revealed a significant and positive correlation between severity and pre- versus post-priming alcohol cue reactivity, primarily within frontal regions including the anterior prefrontal cortex, inferior and superior frontal gyri (Table 4, Figure 4). No significant negative correlation was observed at either threshold.
