  1. a The primary visit is the first visit in level 3 for TRD patients and the visit closest to 141 days from baseline visit and with a deviation ≤60 days for non-TRD patients
  2. Least square means, 95% CIs, and p-values were obtained from a linear model adjusted for baseline of the variable, age category, gender, and baseline values of total severity score of comorbidity, Depression severity by HDRS17, and Depression severity by QIDS-SR16
  3. bWPAI scores are based on 7-day recall period
  4. SFHS Short form health survey, Q-LES-Q Quality of life enjoyment and satisfaction, WSAS Work and social adjustment scale, WPAI Work productivity and activity impairment, TRD Treatment resistant depression, CI Confidence interval
  5. cRange of SF-12 scores reported: Mental Component 13.8 to 67.9; Physical Component 7.4 to 70.5. Lower score indicates poorer mental or physical health-related function and wellbeing
