Figure 4: Significant reductions in one-year graft survival in patients with ASTi >3,500 IU/L compared to patients with ASTi <3,500 IU/L. Kaplan-Meier survival analysis showed the probability of primary graft outcome among patients who had a peak-adjusted AST (ASTi) of greater than 3,500 IU/L along with those who had ASTi of less than 3,500 IU/L. The probability of event-free graft survival at 1 year was 0.576 in the ASTi >3,500 IU/L group and 0.487 in the ASTi <3,500 IU/L group. There was a significant reduction in graft survival in ASTi >3,500 IU/L group.
