A physician at a local hospital has organized a trial that recruits 5,014 pancreatic cancer patients assesses the ability of his newly developed chemotherapy to improve that survival rate. By the end of 5 years of follow up, 376 patients of the original 5,014 were still alive. What is the relative risk in 5 year mortality for the new therapy versus current best medical care

Explanation / Answer
Remember we are being asked the relative risk
relative risk in 5 year mortality for the new therapy versus current best medical care =
Risk of trial - risk of current best medical care
=(376/5016) - 6%
=7.25% - 6%
=1.25%
Answer is D
