natural history study
医疗的	A type of medical research study. In natural history studies, researchers examine how a disease or medical condition develops over time. Researchers follow participants who are at risk for or have a specific disease or condition to determine how specific factors, such as family history, age, and occupational exposure, affect the development or progression of the disease or condition. Data collected during a natural history study also provide information on how best to treat a condition or disease.
