¹SKT_(1-4), solitary kidney transplant, histologic score 1 to 4; SKT_{(> 4)}: Solitary kidney transplant, histological score 5 or higher; DKT: Dual kidney transplant, histological score 5 to 7;

²Right-censored at 6 (DKT) and 10 (SKT) years;

³DGF: Need of dialysis in the first post-transplant week; EGL: Graft loss within 3 mo; PNF: Primary non-function from unknown cause; BPAR: Biopsy-proven acute rejection;

⁴Censored for death with functioning graft;

^aP < 0.03 vs SKT (both categories);

^cP < 0.05 vs DKT.
