§ANCOVA model 1 was built using factors associated with functional disability (total SDS score) in univariate analysis (p<0.05 in ANOVA). ANCOVA model 2 was then built without both PDQ-D and CGI-S. Finally, ANCOVA model 3 was built with PDQ-D, but without CGI-S. Summary of results are presented as p-values. PHQ-9 was an adjustment covariate in all 3 ANCOVA models. **p<0.001; *p<0.05
