Study flow chart. Systematic cross-sectional antibody-mediated rejection (ABMR) screening of a cohort of 741 kidney transplant recipients (BORTEJECT trial) led to the identification of 111 donor-specific antibody (DSA)-positive recipients. Eighty-six DSA+ patients underwent protocol biopsies. For all 86 subjects (primary study cohort) adequate material for KLRC2 genotyping was available. A control group of 106 recipients was defined by propensity score matching as described in the methods section. A large prospective multicenter cohort (Collaborative Transplant Study, CTS; 1,860 recipient/donor pairs) was included to assess associations of genotyping results in relation to long-term allograft outcomes. eGFR, estimated glomerular filtration rate.
