A randomized controlled study investigated whether ingesting vitamin E reduces the incidence of prostate cancer (Klein et al. 2011). Below we provide the 2X2 design (also known as the contingency table) for this study. Calculate by hand the contingency table for expected results, chi-abs (1 point) and relative risk of prostate cancer for people taking vitamin E vs placebo.
