For both measures a value of 1 indicates that the estimated effects are the same for both interventions. The odds ratio (OR) is a ratio of 2 numbers, like the relative risk we have 3 options: OR = 1: The odds in the first group are the same as those in the second. So no evidence that drinking wine can either OR > 1: The odds of having the disease in the exposed group are higher than the unexposed Relative Risk and Odds Ratio for the obese: 3) Overall, you can see that decreasing the baseline incidence will decrease the odds ratio (3.00 in those who are non-obese versus 1.29 in those who are obese).
