Risk factors for post-LT mortality for patients with BMI \u226540 included age &gt;60 y, prior surgery, and diabetes on multivariable analysis. Model for End-Stage Liver Disease &gt;30 was significant on univariable analysis only, likely due to the limited number of patients with BMI \u226540; however, median Model for End-Stage Liver Disease scores in this BMI group were higher than those in patients with lower BMI across all UNOS regions. Patients with BMI \u226540 had a higher waitlist dropout in 4 regions. Comparison with BRFSS data illustrated that the proportion of waitlisted patients with BMI \u226540 was significantly lower than the observed rates of morbid obesity in the general population in 3
