Proportions of benzodiazepine users in three antidepressants groups. Numbers in parentheses above bars are actual number of benzodiazepine users and group participants assessed each week. Benzodiazepine users are defined as patients who took benzodiazepine drugs once or more during the 1-week period prior to each assessment point (weeks 6, 12, and 24). Patients were prescribed benzodiazepines from study day 1. We analyzed differences in the proportions in two groups using Chi-square test at week 6 (a) and Fisher’s exact test at week 12 and 24 (b, c), after the analyses were conducted among the three groups using Chi-square test at week 6 and the Fisher’s exact test at week 12 and 24. P values are based on analyses of Chi-square (a) and the Fisher exact test (b, c)
