Figure 1 shows the data for LTAA, TxN, and the combined NAC group. To insure that the age difference between studies did not confound analysis of group by gender interactions, we reanalyzed each alcoholic group against its own age comparable NAC. These comparisons also showed no group by age effects (p’s ≥ 0.53, effect sizes ≤ 3.3 % of the variance).
