title: Conducting a hospital-based case-control study of the relationship between vasectomy and cardiovascular disease in Korea--an experience in an Asian setting.
abstract: An increasing number of case-control studies are being performed in the developing world. This paper describes the difficulties and advantages the author has experienced in conducting a hospital-based case-control study in the Republic of Korea testing the hypothesis of whether vasectomy is associated with subsequent cardiovascular disease. This experience should provide a useful reference for researchers planning studies using a similar approach in an Asian setting.
