You are a researcher analyzing the potential for teratogenicity of a nutritional supplement, X. You use a longitudinal study design to follow the pregnant mothers and their children until the children reach the age of 4; half the mothers receive the supplement, and the other half receive a control. Your study is designed to assess supplement X's influence on miscarriage and childhood autism. When you calculate the appropriate measure of association for both outcomes of interest, the scores are less than one. Assume the result is statistically significant. Given this information, which of the following statements is most likely true?
The researcher used odds ratio to measure association, and the supplement might cause miscarriage and autism.
You are a researcher analyzing the association of a history of sunburn and skin cancer. You use a retrospective study design that pairs individuals with skin cancer with controls and asks each individual about their sunburn rates as children and young adults. When you calculate the appropriate measure of association for the outcome of interest, the score is greater than one. Assume the result is statistically significant. Given this information, which of the following statements is most likely true?
The researcher used relative risk to measure association, and a history of sunburn might provide a protective benefit from skin cancer.
