highly significantP < 0.001
The overall model was highly significant ( P < 0.001), that is, our model explained the development of CVD better than the null model (model with no explanatory variables), and provided the following cutoff points: optimal , 10 (square root = 0.343); discard , 7 (negative likelihood ratio = 0.07); and confirmation , 14 (positive likelihood ratio = 10.56).
