Barber 2011 United Kingdom end-stage liver disease (UKELD) from INR, creatinine,
Barber 2011 United Kingdom end-stage liver disease (UKELD) from INR, creatinine, bilirubin, and sodium in native SI units. UKELD = 5.395*ln(INR) + 1.485*ln(creatinine_umol_l) + 3.13*ln(bilirubin_umol_l) - 81.565*ln(sodium_mmol_l) + 435, nearest integer. below_listing if <49; listing_threshold if ≥49 (UK elective-list 9% 1-year mortality cut). Not a transplant listing or allocation order. Not MELD or MELD-Na.
