A case-control study was conducted to evaluate the association between oral contraceptive use and breast cancer risk. About 215 breast cancer cases were identified from the city cancer registry and 690 controls were selected from the city population. The use of oral contraceptives was recalled (remembered) by 140 cases and 436 controls. Set up the 2 x 2 Table and calculate the measure of association, provide interpretation. 4. Which type of study is being described in each of the following scenarios (CASE-CONTROL, RETROSPECTIVE COHORT, ECOLOGIC, OR CROSS-SECTIONAL)? Justify your answer. a. A study that examines the death rates from cervical cancer in each of the 50 US states in relation to the average percentage of women in each state undergoing annual PAP smear screening. b. A study that compares the prevalence of back pain among current members of the plumbers and pipe-fitters union with that of current members of the bakers and confectionary union. c. A study that evaluates the relationship between breast cancer and a woman’s history of breastfeeding. The investigator selects women with breast cancer and an age-matched sample of women who live in the same neighborhoods as the women with breast cancer. Study subjects are interviewed to determine if they breastfed any of their children. d. A study of the relationship between exposure to chest irradiation and subsequent risk of breast cancer that was begun in 2005. In this study, women who received radiation therapy for postpartum mastitis (an inflammation of the breast that occurs after giving birth) in the 1940s were compared to women who received a non-radiation therapy for postpartum mastitis in the 1940s. The women were followed for 50-60 years to determine the incidence rates of breast cancer in each group
