CNI withdrawal was associated with borderline significance for worse survival compared to tacrolimus TDM ≥5 ng/mL ( P = 0.067).
CNI withdrawal was associated with borderline significance for worse survival compared to tacrolimus TDM ≥5 ng/mL ( P = 0.067).
Tacrolimus TDM ≥5 ng/mL was associated with a reduced risk of graft failure (HR = 0.54, P = 0.036), while CNI withdrawal showed a trend toward a higher risk of graft failure (HR = 4.37, P = 0.07).
As shown in Supplementary Figure S3 , the early-persistent subgroup exhibited a trend toward lower graft survival, although the difference did not reach statistical significance (log-rank p = 0.26).
