Researchers at the Brigham & Women's Hospital recruited 2,000 participants to study the relation between diet and cholesterol. They hypothesized that persons who eat meat will have higher cholesterol compared to vegetarians. Prior to enrollment all 2,000 participants were carnivores. At the time of enrollment, 1,000 participants agreed to switch to a strict vegetarian diet. After several months the researchers measured the cholesterol levels of the 1,000 carnivores (the exposed group) and the 1,000 vegetarians (the unexposed group) and categorized each participant as having low or high cholesterol

Researchers collected the following data:

  • Among the 1,000 carnivores, 20% had high cholesterol.
  • Among the 1,000 vegetarians, 50 had high cholesterol. [Note: 50 people, not 50%]
