Association between the density of intragraft NK cells and histologic lesions. Mean lesion scores were calculated for each listed histologic lesion (i, interstitial inflammation; t, tubulitis; v, intimal arteritis; ptc, peritubular capillaritis; g, glomerulitis; cg, transplant glomerulopathy; ci, interstitial fibrosis; ct, tubular atrophy). Corresponding Spearman’s correlation coefficients between the density of intragraft NK cells and the listed histologic lesion scores are shown. *P < 0.05.
