Table 4 Regional and age-based rates of fatal bicycle injuries. Rates were calculated by dividing the number of events per region by person-years during the study period, which were estimated by multiplying the population of each region by the study duration (14 years)
From: The epidemiology of fatal cyclist crashes over a 14-year period in Alberta, Canada
