^*Adjustment was performed with Poisson regression models, using generalized estimating equations to account for clustering at the physician level.

^†Adjustment for the following patient characteristics: age, rurality, income quintile, morbidity (resource utilization band) and immigration status.

^‡Adjustment for the following physician characteristics: age, sex, number of rostered patients and whether a Canadian medical graduate.
