  1. EU European Union, LAI long acting injectable, SD standard deviation
  2. a An ANOVA model was fitted with IEQ total score change at end point (DB) from baseline (OL) as the outcome variable, and Study ID as a factor. In addition, variables for baseline characteristics (i.e., region, patient race, prior LAI use) and improvement in employment status were included in the model as a factor one at a time
  3. b Mean (SD) results for Race of “not reported” was not listed due to small sample (n = 1)
