Part 1: Identify the following studies as either case-control, retrospective cohort, or prospective cohort (1 point each). 1. In 1970, researchers recruited 3,725 men and women between the ages of 30 and 62 from the town of Cleveland, Ohio, and began the first round of extensive physical examinations and lifestyle interviews that they would later analyze for common patterns related to cancer development. Since 1970, the subjects have continued to return to the study every two years for a detailed medical history, physical examination, and laboratory tests. 2. Subjects were persons with laboratory confirmed Salmonella enteriditis infection and one healthy friend of each. All subjects were asked about their consumption of produce and poultry products. 3. Vietnamese Experience Study: Subjects were several thousand soldiers stationed in Vietnam from 1969-1971 and several thousand soldiers stationed in Europe form 1969- 1971. In 2000, investigators initiated a study to determine and compare the death rates and prevalence of illness in both groups.
