NCT# stands for National Clinical Trial number. This is a unique identification code given to each clinical trial registered on ClinicalTrials.gov. The format is "NCT" followed by an 8-digit number (for example, NCT00000419). Also called the ClinicalTrials.gov identifier.
Each clinical study has its own guidelines for who may participate, called eligibility criteria.
