a Changes after policy implementation. | ||||||
Note: Baseline level = prescribing rate at month 1 (April 2004); pre trend = monthly change in prescribing rate in period before policy implementation; level change = change in prescribing rate immediately before policy implementation (September 2005) to immediately after policy implementation (April 2006); post trend = monthly change in prescribing rate in period after policy implementation. MMG relative to control estimates are interpreted similarly, but adjusted for concurrent prescribing trends in the control group. | ||||||
