Numbers within the parenthesis next to the labels on the horizontal axis indicate post-transplant years.
KTx: kidney transplantation, eGFR: estimated glomerular filtration rate, IFTA: interstitial fibrosis and tubular atrophy, : %IFTA indicates the proportion of the graft core biopsy specimen showing interstitial fibrosis and tubular atrophy.
