Higher value = greater amount (or higher score on) a particular variable.

^aMain event = received a deceased donor transplant, competing event = received a living donor transplant, died or transplant at a non-VA center, censoring = still on waitlist or other removal.

^bOther pairwise comparisons: black to Hispanic P = 0.123, black to other P = 0.432, Hispanic to other P = 0.612.

^cOther pairwise comparisons: black to Hispanic P = 0.383, black to other P = 0.702, Hispanic to other P = 0.741.

^dOther pairwise comparisons: black to Hispanic P = 0.578, black to other P = 0.532, Hispanic to other P = 0.328.

^eOther pairwise comparisons: site B to site C P < 0.001, site B to site D P = 0.283, site C to D P = 0.001.

^fOther pairwise comparisons: site B to site C P = 0.007, site B to site D P = 0.594, site C to D P = 0.019.
