The analyses of P300 data (Figures 1 and 2) revealed remarkable consistency (Figure 2): Conduct Problems (MANCOVA F8,96 = 2.04, p < .05) and GABRA2 genotype at rs279871 (MANCOVA F8,96 = 2.18, p < .05) were consistent in that both amplified the effects of obesity on P300a latency over the anterior and posterior scalp, and produced greater slowing than was associated with the sum of the main effects of the factors. Table 3 summarizes the results of the univariate analyses.
