MELD and 5vMELD Scores among 1,113 Patients from the Validation Cohort Who Died on the Waiting List.

<p>During the study period, the probability of transplantation within 3 months of listing among patients in the validation cohort was 3.0% in patients with MELD<10, 11.4% with MELD 10–19, 46.9% with MELD 20–29, and 61.3% with MELD 30–39. If 5vMELD had been used to allocate donor organs instead of MELD, an estimated 106 additional transplantations would have been performed as calculated according to the following formula: 24×(11.4%−3.0%)+5×(46.9%−3.0%)+216×(46.9%−11.4%)+3×(61.3%−11.4%)+166×(61.3%−46.9%). Therefore, 9.5% of the deaths (106/1,113) that occurred with 3 months of listing might have been prevented had 5vMELD been used instead of MELD.
