Results of the model comparison among the full ADE Cholesky model and sub-models.

Sample: MZ (N = 219 pairs) and DZ (N = 244 pairs).A = additive genetic factors; C = shared environmental factors; D = non-additive genetic factors; E = non-shared environmental factors; AIC = Akaike information criterion; df = degree of freedom; MZ = monozygotic; DZ = dizygotic.The most suitable model is shown in bold, having the lowest AICResults of the model comparison among the full ADE Cholesky model and sub-models.
