R2 (p value) given for multivariate models (n=150 patients*).
*A few patients left some of the rows empty (see statistics under the methods section). Both the dependent and independent variables are mean scores. Only those variables exhibiting a significant relationship in either bivariate or multivariate analyses are shown (see statistics under the methods section for which variables that were included in the analyses).
