Risk Factors for Surgical Site Infections (SSI): Results of our univariate analysis to identify predictors of SSI. Among the donor,
recipient and operative characteristics analyzed utilizing the cox regression model- only re-transplantation was associated
with a significantly increased risk of SSI (P = 0.015).
