Question 13 A study is planned to investigate the relationship of factors associated with maternal hypertension and the risk of congenital birth defects in children born to these women. In this study, the researchers will start with women who have given birth to children with birth defects. They then research their charts to determine their hypertension levels during their pregnancy. What should be your measure of rate, odds or risk ratio? rate odds risk ratio What type of study is...

Match the type of epidemiology/study with the example This type of study is the strongest at proving or disproving association and allows the researcher to control exposure to cases and controls. Examples of this type of a study include BRFSS, NHANES, PRAMS. This is (or these are) not a study but a form of epidemiology that includes analyzing rates, proportions, and ratios. This type of study is (or these types of studies are) most often used with testing a null...
Scenario 2: Effects of Tea A group of researchers are interested in the potential anti-carcinogenic effects of tea. Given new reports of increased incidence of breast cancer in their town, they wanted to determine if there was any association between breast cancer and tea consumption as the exposure. They enrolled 25 women with breast cancer, and 50 women without breast cancer for their study. What type of study design was used?
