A clinical trial is run to assess the efficacy of a new drug to reduce high blood pressure. Patients with diagnosis of hypertension (high blood pressure) are recruited to particpate in the trial and randomized to receive either the new drug or placebo. Participants take the assigned drug for 12 weeks and their blood pressure status is recorded. At the end of the trial, participants are classified as still having hypertension or not.

a. What is the prevalence of hypertension at the end of the trial?

Prevalence₂₀₀₅= 20/100

b. Estimate the relative risk comparing the proportions who are free of hypertension at 12 weeks between groups.

Relative Risk = .1363/.3888 = 3.5
