aPHQ-9: Patient Health Questionnaire-9; range 0-27, higher is more depressed.
bFrom mixed-effects linear regression models adjusted for study site, consulting psychiatrist, and language of the interview, as well as clustering due to patient and primary care physician.
cATP: asynchronous telepsychiatry.
dNot available.
eSTP: synchronous telepsychiatry.
