Note: Q1 to Q5 represent quintiles, where Q1 = lowest quintile and Q5 = highest quintile for the quantity of incentive-eligible services provided in the pre-incentive period.
All estimates are presented with 95% confidence intervals.
Confidence intervals on model estimates were calculated with bootstrap standard errors (using 1000 replications). All estimates are conditional on other model covariables (not reported).

The level change in the mean monthly number of visits after introduction of the incentives.
The change in the trend for mean monthly number of visits after introduction of the incentives, compared with the monthly trend before introduction of the incentives.
The monthly change in the mean number of visits after introduction of the incentives.
