To determine whether the percentage of CD19+CD24hiCD38hi Bregs is independently associated with GFR in renal transplant recipients, we conducted a multiple multivariable regression analysis to account for the following potential confounders: Age, cold ischemia time, delayed graft function, HLA mismatches >3 (A, B, DR), CMV infections, BK‐nephropathy, rejections, and CRP. The gene discussed is CD19; the disease is cytomegalovirus infection.
