The association between job-related exposure to welding fumes and chronic obstructive pulmonary disease (COPD) was explored in a case-control study. The following data were reported for 399 COPD patients: 37 currently employed as welders; the remainder had no occupational exposure. Among 800 controls, 48 were employed as welders. Set up a 2 by 2 table and calculate the OR (odds ratio) between welding and COPD.
Why would you exclude women who cannot develop the disease as controls in a case-control study of gynecologic cancer?

OR (aerobic exercise and dental caries) + 1 (not significant)
OR (exposure to side-stream cigarette smoke and lung cancer) + 1.3
OR (infectious disease of the pelvis and ectopic [tubal] pregnancy) + 3.0
