a marginal trend toward significanceP = 0.052
While the main effect of 5- HTT in women showed a marginal trend toward significance ( P = 0.052), with a medium effect size, the planned pairwise comparison indicated that women with 5- HTT- SS tended to have a higher angry MMN amplitude than women with 5- HTT- LL/LS (3.084 ± 0.424 μV, 1.788 ± 0.501 μV, P = 0.052, respectively).
