What could you conclude if you were given the following measure of association: Relative Risk = 0.89 (95%CI: 0.76- 1.04)?

a. A case-control study was used to estimate this relative risk estimate.

b. The exposure is a risk factor.

c. The relative risk estimate is not statistically significant.

d. There is a causal relationship between the exposure and the outcome.

Answer #1

Null value for the relative risk is 1, i.e. there is no different of risk between the control group and the test group

Given confidence interval range 0.76 to 1.04

it is clear that the null value of 1 is included in the confidence interval for the relative risk, which means that there is no significant difference between the control group and test group on the basis of relative risk.

So, option C is correct answer, i.e. it is not significant

Option C is answer

Effect measure modification occurs when the strength of an association varies according to the level of a third variable which is called an effect measure modifier. Confounding is the distortion of the association between an outcome of interest and an exposure because an important third variable has not been accounted for; this third variable is called a confounder.

Pregnant women were recruited during their first trimester to study the relationship between chocolate consumption during pregnancy and risk of preeclampsia (pregnancy-induced hypertension). They were interviewed about chocolate consumption, age, race, education, smoking, body mass index, and previous pregnancy history. Participants were re-interviewed after delivery to obtain information on chocolate consumption during the third trimester of pregnancy. In addition, umbilical cord blood was collected at the time of delivery and measured for concentration of theobromine (the major metabolite of chocolate)....
