Relative weights of the variables (which were selected as being positively and significantly associated with the CGI-SCH score with the p value < 0.05 in Table 2) are presented as a set of magnitudes of multiple regression coefficients (p < 0.001). R-squared was 0.7198 (the subset of eight items resulted from stepwise regression using three small sets) and p value of analysis of variance was less than 0.001.
