aThe study periods were 1 year before and 1 year after the implementation of SARA (Service Apothecary Respiratory Advice; in Dutch, Service Apotheek Raad en Advies).
bThe difference score was calculated as the exacerbation rate the year after SARA minus the rate the year before SARA; values are only reported in the “1 year after” rows.
cStatistics comparing study groups are reported only in the top row of values.
