AIC, Akaike information Criterion; Δdf and Δχ² calculated from full model; n/a, not applicable; A, heritability component; C, common environment component; E, unique environment component; r_a, GAD/AN genetic correlation; r_c, GAD/AN shared environmental correlation; r_e, GAD/AN unique environmental/error;

indicates best fit.
