The PHQ-9 was administered to all participants in the prestudy visit questionnaire (but was not disclosed to study providers).
↵* Based on a review of the study visit note in the medical record. Values are adjusted for nesting of patients within providers; trial intervention group; trial stratification variables (practice setting [academic versus nonacademic], patient sex, and patient race/ethnicity category [non-Hispanic white or all others]); and trial sample weighting (ie, oversampling of people with higher levels of depressive symptoms [PHQ-9 score >5]).
AOR, adjusted odds ratio; CI, confidence interval; PHQ-9, 9-item patient health questionnaire.
