  1. Data are presented as mean and standard deviation unless otherwise indicated. Covariates are given as measured at the time of kidney transplantation. TCMR acute T-cell mediated rejection, ABMR acute antibody-mediated rejection, DCGF death-censored graft failure, HLA human leukocyte antigen, ESRD end stage renal disease, DM diabetes mellitus, HTN hypertension, GN glomerulonephritis, eGFR estimated glomerular filtration rate. The multivariable model was adjusted for age, smoking, BMI, hypertension, DM, sex, HLA mismatch, cause of ESRD, serum phosphorus, albumin, eGFR at 6 months, preemptive, annual mean PM10, donor age, sex, donor type, and ABO-incompatible
