Suppоse а grоup оf reseаrchers аimed to determine if maternal infections during pregnancy could be a cause of cerebral palsy in American children. Cerebral palsy is a relatively rare disease, as about 3 children per 1,000 American children have cerebral palsy. The researchers decided to perform a case-control study with children aged 18 or younger and living in Hillsborough County as the population of interest. They included all children with cerebral palsy and a random sample of children without cerebral palsy. The researchers estimated an exposure odds ratio of 2.04. The researchers claim that their exposure odds ratio of 2.04 can be interpreted as an outcome risk ratio. Why can the exposure odds ratio be interpreted as an outcome risk ratio in this case? (max. 6 points).

A grоup оf reseаrchers аimed tо determine if women who used orаl contraceptives are at an increased risk of stroke compared to women who used non-hormonal methods for birth control. To determine this association, researchers randomly selected a group of women who were 18 years or older and lived in Tampa in 1970. For these women they requested medical records from local physicians and classified the women as either having used oral contraceptives or having used non-hormonal methods for birth control. Subsequently, the researchers requested access to current medical records to determine which women developed stroke. Finally, to determine if stroke was more common among women who used oral contraceptives than among women who used non-hormonal methods for birth control, they estimated a risk ratio. What study design did the researchers use?
