The Physicians' Health Study

The Physicians' Health Study was a large research project started in 1982 involving male doctors to investigate whether certain medications could prevent heart disease and other health issues. Participants were randomly assigned to receive aspirin, vitamins, or placebos, and their health was monitored over many years. The study provided valuable insights into the roles of aspirin in reducing heart attacks and the effects of vitamins, shaping guidelines on disease prevention. Its rigorous design helped establish evidence-based practices that benefit public health.
