The PELD score did not accurately predict 90-day pretransplant mortality in children who were listed for liver transplantation compared with adults in a similar situation, according to data published in JAMA Pediatrics.

Chang, PhD, from the University of Pittsburgh in Pennsylvania, and colleagues wrote. “Children may be disadvantaged in the current organ allocation system compared with adults, a situation that most of society would find untenable.”
