Comparison of age- and gender-specific prevalence estimates of hypertension based on complementary data sources. Hypertension was defined as drug use alone in Swiss Health Survey (SHS), as drug use alone in primary care data (FIRE), and as ICD-10 codes I10-I15 or I67.4 as secondary diagnoses in hospital discharge statistics (MEDSTAT). Results based on less than 30 observations are marked by an asterisk. (Data sources: Swiss Federal Statistical Office for Swiss Health Survey [SHS] and Hospital Discharge Statistics [MEDSTAT]; Swiss Family Medicine International Classification of Primary Care Research using Electronic Medical Record project for primary care data [FIRE]).
