Adjusted difference represents the immediate change in the week of policy implementation, change in slope represents difference between slope of fitted linear model on either side of policy implementation, both from interrupted time-series analyses with controls for weekly volume, clinician-level fixed effects, and robust standard errors clustered at the clinician level.
