Figure 2. Kidney graft survival according to the most sensitive modality performed among crossmatchnegative kidney transplants, 1999-2005. P-value by the Log-Rank test. “X” symbols in the legend indicate the tests being compared. Five-year, cumulative graft survival after transplant with negative T&B FC crossmatch as the most sensitive technique (82.6%) was modestly better than after negative T AHG &B crossmatch (81.4%; P=0.008) or T AHG crossmatch (81.1%; P<0.0001). Five-year cumulative graft survival was not appreciably different after negative T AHG &B compared to T AHG crossmatch (81.4% versus 81.1%, P=0.05).
