In one randomized controlled trial, patients with non-bleeding esophageal varices using beta-blockers had a 4% risk of developing variceal bleeding during two years of follow-up. However, patients using placebo had a 24% risk of variceal bleeding. What is the relative risk reduction (RRR) and the absolute risk reduction (ARR) in variceal bleeding associated with the use of beta-blockers in this trial?
RRR = 82% and ARR = 20%
RRR = 20% and ARR = 83%
RRR = 26% and ARR = 15%
RRR = 88% and ARR = 26%
