We wish to design a study to assess risk factors for stroke and dementia. There are two primary outcome measures. The first is a measure of neurological function. Patients with “normal” function typically score 70 with a standard deviation of 15. The second outcome is incident stroke. In patients over the age of 65, approximately 14% develop stroke over 25 years. How many participants over the age of 65 must be enrolled to ensure the following?
