Researchers were examining potential associations between (exposure) smoking and (disease) acute myocardial infarction (AMI). They selected 500 adults who were in the hospital for AMIs and matched them with 500 adults also in the hospital for other non-related reasons. The researchers then looked back in medical records to identify if the sample reported smoking in the past. Of the 500 with AMI, 348 were found to be smokers and of the 500 without disease, 115 were found to be smokers.(a) What is the study design?(b) What is the answer to the main calculation of association in this study? (If it is a cohort or experimental study only produce the relative risk or risk ratio.) (c) What is an important issue associated with this study design?
