^*Multivariable model included three time-varying covariates: MELD score, exception score (yes/no), and temporally inactive status (status 7)

^†Reported P-values are from the multivariable model

^‡Age reported as increased hazard ratio for every increase in 10 years of age

^**Insurance is coded as private if the UNOS code for insurance equals private, and public if the insurance is coded as public (defined by UNOS as Medicare, Medicaid, or other governmental insurance).
