- Incidence rate of dementia (cases/1000 person-years) = the number of patients with newly developed dementia during the observation period (cases)/the total person-years of the target patients during the observation period (person-years) × 1000. The length of follow-up for patients with dementia was assumed to be 0.5 years
- CI confidence interval
