atch each description to the correct study design. Study designs may be used more than once. + Incidence data is not available with this study design, so an odds ratio is an appropriate measure of association to calculate. . - . - + This study design allows for the evaluation of multiple outcomes. + The temporal sequence between the exposure and outcome is clear for this study design; therefore, incidence data available and a risk ratio can be calculated. With this study design, exposure status is assessed, and then participants are followed up over time to see who develops the outcome. + Recall bias is a common issue with this study design because exposure information is collected from the past. QUESTION 2 A. Cohort study B. Case-control study onsider the following scenario for the questions that follow. a recent case-control study, investigators enrolled 300 adults with heart disease and 300 healthy adults. During interviews with the participants, the investigators determined participants' use of multivitamins childhood, which was dichotomized into yes or no. What is the null hypothesis for this study? There is no association between multivitamin use during childhood and heart disease. Multivitamin use during childhood decreases the odds of heart disease. Multivitamin use during childhood decreases the risk of heart disease. Multivitamin use during childhood increases the odds of heart disease.
