Figure 4. Kaplan-Meier analysis-estimated probability of allograft survival of the three risk groups of transplant glomerulopathy.

Figure 4

We used the linear predictor from the final Cox model to construct a prognostic index (PI) for each patient. Based on the PI we divided arbitrarily the entire cohort into three risk groups for allograft failure; low risk (<30th percentile of the PI, cut off: 1.54), medium risk (30th-70th percentile) and high risk (>70th percentile of the PI, cut off: 2.34). Figure depicts the Kaplan-Meier estimated probability of allograft survival for the three risk groups. The median allograft survival was >60 months from the diagnosis of TG for the low risk group, 25 months from the diagnosis for the medium risk group and 3.7 months from the diagnosis for the high risk group. The hazard ratios for allograft failure were 2.83 (1.39–5.75) and 5.96 (2.91–12.19) for the medium and high risk groups, respectively, compared to the low risk group. Table depicts the estimated allograft survival at various time points after the diagnosis.
