Geo-map on ischemic stroke incidence in the population aged 70+ years, calendar period 2006–2010, in the municipality of Halmstad, Sweden; divided into 12 parishes. The ischemic stroke cases were obtained from the regional in-patient registry (in total, n = 959). The smoothed standardized incidence ratios (SIRs) for each parish are shown (range: 0.80-1.13), which reasonably reflect the predicted SIRs for the target population, provided unchanged impact of underlying risk factors.
