Observed (outcomes) vs. Expected (outcomes). Refers to the organs transplanted measure introduced by the OPTN in 2011. It is expressed as a ratio of observed organs transplanted over expected organs transplanted. A score of 1.0 means the observed and expected are equal; <1.0 = less organs transplanted than expected; > 1.0 = more organs transplanted than expected.
