Age- and gender-specific prevalence estimates of diabetes mellitus 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 diabetes. For primary care data (FIRE) (c and d), we defined cases as drug use alone, drug use or diagnosis, and drug use or diagnosis or serum glucose measurement (serum glucose ≥11.1 mmol/L or HbA1c ≥6.5%). For hospital discharge statistics (MEDSTAT) (e and f), we defined cases as ICD-10 codes E10-14 as secondary diagnoses. 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]).
