  • Finding ways to prevent the initial development or recurrence of a disease or condition. These can include medicines, vaccines, or lifestyle changes, among other approaches.
  • Evaluating one or more interventions aimed at identifying or diagnosing a particular disease or condition
  • Examining methods for identifying a condition or the risk factors for that condition Exploring and measuring ways to improve the comfort and quality of life through supportive care for people with a chronic illness
