  1. Crude prevalence estimates for diabetes mellitus, treated diabetes, ischaemic heart disease, heart failure and COPD in 5 Italian regions, according to administrative data (Admin) and clinical GP data (GP). For diabetes and COPD only: crude prevalence estimated from the National Health Survey (Surv). For diabetes only: prevalence estimates from administrative data adjusted for estimated completeness of ascertainment (Admin-Recap). Prevalence estimated both as global percentage with 95% confidence interval and, for Admin and GP only, as median with interquantile range of the distribution of prevalence in GP practices. Date: 1 January 2009. Population: male and females, aged 16-95 in GP and 16+ in the other sources.
