Suppоse а teаm оf reseаrchers cоnducted a prospective cohort study on the effect of physical activity on the 6-month risk of depression. To assess potential effect modification by gender, the researchers estimated the effect of physical activity on depression separately for men and women. In men, the estimated risk difference was -0.11 and the estimated risk ratio was 0.71. In women, the estimated risk difference was -0.07 and the estimated risk ratio was 0.80. Based on these effect estimates the researchers concluded that gender is indeed an effect modifier, so the researchers decided to report the conditional effect estimates in their manuscript.   Please provide an interpretation of the estimated risk ratio of 0.71. Make sure to incorporate the number 0.71 in your interpretation and assume that physical activity was the exposure level of interest and physical inactivity was the comparison level. (max. 4 points)
