Figure 4

No significant differences in persistence of HLA antibodies between CR− and CR+ recipients. Longitudinal class I (A and B) and class II (C and D) HLA Ab NBG ratios were plotted over time for CR− (A and C) and CR+ recipients (B and D). The dashed line marks the cutoff used to distinguish positive and negative results. Kaplan-Meier survival analysis was used to evaluate the persistence of new class I (E) and class II (F) antibodies, with CR− and CR+ recipients compared using the log-rank test and associated P values reported.
