LTAA DAO vs. NSAC: Comparing NSAC and LTAA DAO, the multivariate test was marginally significant (Wilks' λ7,111 = 0.887, p = .059), with smaller volumes in LTAA DAO for the accumbens (F1,117 = 4.17. p = .043, es = 3.4), hippocampus (F1,117 = 6.41, p = .013, es = 5.2), pallidum (F1,117 = 5.08, p = .026, es = 4.2), putamen (F1,117 = 4.92, p = .028, es = 4.0),and thalamus(F1,117 = 4.90, p = .029, es = 4.06). Including age as a covariate did not change the results.
