  1. HR, hazard ratio, CI, confidence interval, RDW, red cell distribution width, TPL, transplantation, DWGF, death-with-graft-function, DCGF, death-censored graft failure. aMultiple imputation by CART (classification and regression trees) was performed. bAdjusted for age (continuous, years), sex, smoking history, eGFR (categorical, <30, 30–60, ≄60), post-transplant RDW (continuous, %), hypoalbuminemia (categorical, serum albumin <3.0 g/dL), presence of acute rejection (within post-TPL 3 month), baseline diabetes mellitus, hypertension, whether induction therapy was performed, medication use of tacrolimus, donor relationship (categorical,Ā deceasedĀ or living). cCalculated time-averaged values (Hemoglobin, eGFR, albumin and RDW) between 3–12 months from operation were used in the analyses. In the analyses using the time-averaged values, the mortality or graft failure cases before 12 months were not included.
