  1. *Controlled only for Cluster Randomization.
  2. †Poisson regression (continuous variable unless otherwise stated) controlling at the level of the clinic: cluster randomization and the pre-intervention rate for that group; at the level of the physician: the number of years in practice; at the level of the practice demographics: mean proportion of patients seen per half-day and average number of visits per patient; and at the level of the patient: mean age, comorbidity (categories of 0, 1, 2), and mental health diagnosis (categories of Y, N).
  3. ‡For model stability, unable to adjust for mean patient age.
