Fig. 1. (A) Mean difference from baseline in PHQ-9 scores. (B) Mean difference from baseline in CGI-S scores. Error bars represent 95% CI of mean difference. Linear mixed model was used to compare the measurements in the follow-up visits versus baseline. Visit was the only factor in the model. PHQ-9, Patient Health Questionnaire-9; CGI-S, Clinical Global Impression–Severity; CI, confidence interval; SD, standard deviation.
