QUESTION 30 Q30. A cohort study measured a relative risk (RR) between Exposure X and Disease Y of 1.5. Based on this, we can conclude that: O Exposure X caused Disease Y O Individuals exposed to Exposure X had a 50% increase in risk of Disease Y compared to the unexposed group, O Individuals exposed to Exposure X had 1.5 times the risk of Disease Y compared to the risk in the unexposed. O B and C O A, B, and C QUESTION 31 Q31. An investigator hypothesized that obesity was associated with increased risk of cancer. They conducted a study in Country A on the risk of cancer investigating obesity as a risk factor and reported a relative risk (RR) of 1.30 (95% CI 0.31-5.37); this measure of association compared obese individuals to normal weight individuals. Based on this, we can conclude the following: O If we repeated the study 100 times, 95 of those times the true value would be between 0.31 and 5.37. O Obese individuals had 130% greater risk of cancer compared to normal weight individuals. O There is insufficient evidence to conclude that the risk of obese individuals is statistically significantly different from the risk of normal weight individuals. O A and B O B and C O A and C QUESTION 32 Q32. The investigator in Q30 conducted a similar study in a new study population in Country B. The relative risk for the association between obesity and cancer in Country B was 1.1. They conducted statistical significance testingt O We can reject the hypothesis that obesity is associated with increased risk of cancer in Country B. O We cannot reject the hypothesis that obesity is associated with increased risk of cancer in Country B. O We can reject the null hypothesis that there is no difference in risk of cancer comparing obese and non-obese individuals in Country B. O We cannot reject the null hypothesis that there is no difference in risk of cancer comparing obese and non-obese individuals in Country B. the RR of 1.1 and calculated a p-value of 0.06. Based on this, we can conclude the following:
