aPHQ-9: Patient Health Questionnaire.
bThe enrolled patients with PHQ-9<10 at the point of enrollment were included in the data set of the study due to the health care providers’ discretion. The patients met other eligibility criteria and were diagnosed with depression. The clinical reasons for inclusion of these subthreshold patients were varied and included a previous pattern of relapse or a concern that the patient was minimizing their symptoms.
