  1. Forward selection step-wise linear regression analysis of the each test variable was conducted using MADRS, YMRS, subdiagnosis, history of psychosis, anxiety disorder and ADHD co-morbidity and use or non-use of each medication group as independent variables. Only significant predictors for each test variable are listed in the table. 1Variable was log-transformed prior to analysis.
