Our polymorphism was in Hardy–Weinberg equilibrium in both independent populations (Budapest P=0.79 and Manchester P=0.91) and in the combined sample (P=0.77). Pearson's correlations were calculated between the four subscales of the List of Threatening Experiences questionnaire in the combined sample, resulting in significant but negligible weak correlations with the exception for the correlation between RLE-relationship and RLE-social, as well as RLE-financial and RLE-social, which were nonsignificant (Supplementary Table S1).
