Overprescribing
Increasing (round 2 prescribing higher than round 1, indicating change not consistent with NCEP guidelines)	927	25.3 (0.87)	70.5 (1.10)	45.1 (1.02)
Stable (vignette responses in both rounds are the same but non‐zero, indicating no change consistent with NCEP guidelines)	276	82.2 (2.00)	82.2 (2.00)	0.0 (0.00)
Decreasing (round 2 prescribing less than round 1, indicating change consistent with NCEP guidelines)	471	68.0 (1.59)	27.2 (1.90)	−40.8 (1.82)
