Figure 11: Estimates of the annual prevalence of problem opioid use (among population aged 15-64)

Annual report figure


A symbol indicates a point estimate; a vertical mark indicates an uncertainty interval: a 95 % confidence interval, or one based on sensitivity analysis. Target groups may vary slightly, owing to different estimation methods and data sources; therefore, comparisons should be made with caution. Non-standard age ranges were used in the studies from Finland (15-54), Malta (12-64) and Poland (all ages). All three rates were adjusted to the population aged 15-64. For Germany, the interval represents the highest and lowest bounds of all existing estimates, and the point estimate a simple average of the midpoints. Methods of estimation are abbreviated: CR, capture-recapture; TM, treatment multiplier; MM, mortality multiplier; CM, combined methods; TP, truncated Poisson; PM, police multiplier; OT, other methods. See Figure PDU-1 (part ii) and Table PDU-102 in the 2011 statistical bulletin for further details.
