Among those who are not pregnant at the time of survey, 40% reported using OCPs in their gardens in the last year while they were trying to conceive. Assume minimal loss to follow-up and no competing risks. a. Which study design is described above? Case-control study Closed cohort study Open cohort study Cross-sectional study Ecologic study None of the above B. Draw a 2x2 table based on the description above. Identify and label the exposure and the outcome. Be sure to include any appropriate totals based on the respective study design.
