a
Outcome variables were coded as follows: 1=remission, 2=response wo remission, 3=none.
b
Odds ratios estimated using an ordinal logistic regression, adjusted for baseline PHQ9 score
c
Odds ratios estimated using an ordinal logistic regression, including only variables from Model 1 with p<.2, adjusted for all other variables in the model
d
In Model 1, the OR for PHQ9 score is an unadjusted estimate
