Eligibility Criteria

The eligibility criteria are a guideline that lists the requirements for a subject to be included (inclusion criteria) or excluded (exclusion criteria) from participating in a study.

The characteristics described in the eligibility criteria must be shared by all participants. These criteria may include:

  • Age
  • Gender
  • Medical History
  • Current Health Status
  • Medications

The eligibility criteria allow for a certain amount of standardization amongst study participants and help obtain accurate and meaningful results. The exclusion criteria also decrease the potential for adverse effects by excluding those most at risk from the exposure to the intervention.
