What is the estimated odds ratio of cases when analyzing this study as a matched case-control study design? Use the information from a case-control study table: Exposure Status by Disease Status Pair no Cases Controls Exposed Unexposed Exposed Exposed Exposed Unexposed Exposed Exposed Unexposed Exposed Unexposed Unexposed Exposed Exposed Unexposed Exposed Unexposed Unexposed Unexposed Unexposed Exposed Exposed Unexposed Exposed Exposed Unexposed Unexposed Unexposed Exposed Unexposed 2.25 1.00 0.50 0.67

A matched case-control study design can be used to help control for confounding factors. In a case-control study, investigators examine disease A and exposure B and match individuals based on race and ethnicity. They have a two by two table of discordant and concordant matched pairs. Calculate the odds ratio for the matched case-control study. Controls, Exposed Controls, Non-Exposed Cases, Exposed 658 215 Cases, Non-Exposed 112 544
