ATG, antithymocyte globulin; CMV, cytomegalovirus; HCV, hepatitis C virus; HDL, high-density lipoprotein; HLA, human leukocyte antigen; HR, hazard ratio; IL-2Ra, interleukin-2 receptor antagonist; PTDM, posttransplantation diabetes mellitus; TG, triglyceride.
Adjusted for age, sex, race/ethnicity, history of cardiovascular disease, cause of end-stage renal disease, duration of pretransplantation dialysis, year of transplantation, number of prior transplantations, body mass index, history of hypertension, serum TG and HDL-cholesterol level, blood hemoglobin level, erythropoietin use, HLA mismatch, donor type and age, HCV and CMV serostatus, immunosuppressive agents, and time between date of HbA1c measured and date of transplantation.
Anemia was defined as blood hemoglobin < 11 g/dl.
Not exclusive categories.
Low HDL-cholesterol was defined as < 40 mg/dl in men and < 50 mg/dl in women.
