Multivariate regression analyses used transformed AAO (sqrt(AAO)) that fulfilled the normality assumption (Shapiro-Wilk W = 0.98; p > 0.05). No significant result was observed when studying physical neglect, physical abuse, nor sexual abuse. We found an interaction between emotional abuse and ‘LS’ genotype on the AAO (p = 0.02) and a trend for an interaction between emotional neglect and ‘LS’ genotype on the AAO (p = 0.08). No interaction was found with ‘SS’ genotype in both models (see Tables 3 and 4).
