An additional 373 recipients who were followed for less than 1 yr and were alive at last follow up are not shown in this table but are included in all subsequent analyses. Factors are listed in order from highest to lowest variable importance.

AST indicates aspartate aminotransferase; BMI, body mass index; CDC, Centers for Disease Control; COD, cause of death.
