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 StrokeBaseline: Not hypertensive 1000 50Baseline: Hypertensive 300 501. Compute the cumulative incidence of stroke in patients classified as hypertensive at baseline. A) 0.20B) 0.50C) 0.0625D) 0.05

None of the options are correct.

The cumulative incidence of stroke in patients classified as hypertensive at baseline = 0.625

Step-by-step explanation:

The table properly drawn is that

Baseline - Not hypertensive

Free of stroke at 5 years | Stroke | Total

1000 | 50 | 1050

Baseline - Hypertensive

Free of stroke at 5 years | Stroke | Total

300 | 501 | 801

Compute the cumulative incidence of stroke in patients classified as hypertensive at baseline.

Number of patients classified as hypertensive at baseline = 801

number of stroke incidents amongst patients classified as hypertensive at baseline = 501

The cumulative incidence of stroke in patients classified as hypertensive at baseline = (501/801) = 0.625
