A cohort study is conducted to assess the association between clinical characteristics and the risk of stroke. The study involves n = 1370 participants who are free of stroke at the study start. Each participant is assessed at study start (baseline) and every year thereafter for 5 years. The following data were collected relating hypertensive status measured at baseline to incident stroke over 5 years.
|Free of Stroke at 5 years||Stroke|
|Baseline: Not hypertensive||1000||50|
Compute the cumulative incidence of stroke in patients classified as hypertensive at baseline.
I followed the directions as shown in a similar question 20/70 patients with hypertension and stroke divided by patients with stroke however, I do not come up with a correct answer
