Numbers shown are percentages with (95% confidence intervals). The ICD-10-SW codes used for defining the disease groups were following: hypertensive diseases 110–115, Ischemic heart diseases 120–125, heart failure 150, valvular diseases 133–139, and other cardiac diseases 105–108, 127–128, 130–131, 140–143, 151. Vascular diseases included cerebrovascular diseases 160–169, other arterial diseases 170–179, other venous diseases 180–189 and other vascular diseases 195–199. Gastrointestinal diseases were defined by K00-K93 whereof inflammatory bowel diseases by K50-K52. Infectious diseases included A00-B99 and J00-J22, injuries 500–599 and T00-T99, and malignanciesC01-C97
