Candidates concurrently listed at multiple centers are counted once. Candidates who are active at at least one program are considered active; otherwise they are inactive. Active status is determined on day 7 after first listing. A new patient is one who first joined the list during the given year without ever listing in a prior year, or one who listed and underwent transplant in a prior year and relisted in the given year.
