Age- and gender-specific prevalence estimates of hypertension based on complementary data sources and various definitions. For health survey (SHS) (a and b), we defined cases as drug use alone, and drug use or diagnosis of hypertension. For primary care data (FIRE) (c and d), we defined cases as drug use alone, drug use or diagnosis of hypertension, drug use or diagnosis of hypertension or measurement of increased blood pressure. For hospital discharge statistics (MEDSTAT) (e and f), we defined cases as ICD-10 codes I10-I15 or I67.4 as secondary diagnoses.
