Development in the consumption for two Danish practices, before and after the initiation of the measures for the reduction of benzodiazepines (N05BA, N05CD) and cyclopyrrolones (N05CF). Data compiled before the intervention is derived from prescriptions are quarterly averages for the four quarters of 2003; data for prescriptions issued after the initiation of the measures are for the last two quarters of 2005 and the first two quarters of 2006. Error bars denote the 95% confidence interval of the means. “Before” and “After” values are significantly different, (P < 0.05; two-tailed T-test for samples with equal variance)
