VanWagner LB et al. A point-based prediction model for cardiovascular risk in orthotopic liver transplantation: the CAR-OLT score. Hepatology. DOI: 10.1002/hep.29329. PMID: 28703300. Table 3 points: age under 45 is 0, 45–49 is −6, 50–54 is −4, 55–59 is 2, 60–64 is 5, and 65 or older is 8; men 0 and women 1; White 7, Black 10, and other race or ethnicity 0; not working for income 10; high school or unknown education 5 and college or higher 0; atrial fibrillation 25; respiratory failure on a ventilator at transplant 13; pulmonary hypertension 9; absence of hepatocellular carcinoma 6; systemic hypertension 4; diabetes 4; heart failure 7. History of each condition is coded before transplant. Table 4 prints 1-year absolute risk under 5% for a score under 9 (green, very low), 6% for 10–12 and 8% for 13–15 (unshaded, low), 10% through 26% for 16–30 (yellow, moderate), 30% through 38% for 31–36 (orange, high), and 40%, 43%, and 45% or higher for 37–38, 39–40, and above 40 (red, very high). Table 4 does not print a row for score 9. (2017)
