Figure 1: Kaplan-Meier plots for major graft functional decline (defined by graft loss or doubling of serum creatinine after the diagnosis of BKV-viremia) in either groups of patient stratified by Treatment Group. Major graft functional decline rate was significantly different: Group 2 had 13% of major graft functional decline rate at the end of follow-up while Group 1 had 36% of major graft functional decline rate (p < 0.001).
