The study population included 5,000 individuals at baseline, with 200 participants aging out of the study (turning 76) each year and 150 new participants entering each year (turning 50). After 4 years, 180 stroke events were recorded. Assuming uniform age transitions throughout each year and no other losses to follow-up, what is the incidence rate?
