A clinical trial is run to assess the efficacy of a new drug to reduce high blood pressure. Patients with a diagnosis of hypertension are recruited to participate 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 is recorded. At the end of the trial, participants are classified as still having hypertension or not. The data are shown below. The Estimated relative risk comparing who are free of hypertension at 12 weeks between groups is:

group # randomized # free of hypertension at 12 weeks

placebo 50 6

new drug 50 14

A. 0.43

B. 1.2

C. 4.0

D. 2.33
