AIC = Akaike information criteria; df = degrees of freedom; MD = major depression.

↵* All models include (A) 5-HTTLPR triallelic, (B)

*BDNF*Val66Met and (C) childhood maltreatment as risk factors and sex, age and baseline MD as covariates.↵† Degrees of freedom are associated with the analysis of every AIC model.

↵‡ AIC-minAIC shows the difference between every AIC with respect to the lowest AIC value in each category. Differences lower than 3.84 (1.96

^{2}) make the model statistically as good as the model with the minAIC value.
