CDA = canonical discriminant analyses; CGI-BP = Clinical Global Impressions Bipolar; HAM-D = Hamilton Rating Scale for Depression; SCC = standardized canonical coefficient; YMRS = Young Mania Rating Scale.

Bold: highest ranked variable to discriminate groups according to SCC; Italic: variable that contributed the most to differentiating participants in their original groups, according to Wilk’s lambda.
