The viremia rates (% ± standard error [SE]) at 5 years after transplant (Tx) were estimated by the Kaplan-Meier method and the group differences were assessed by the log-rank test. Results for 1st viremia, peak levels, duration, and time for BKAN are mean ± standard deviation. m post-Tx: months after transplant, PTLD: posttransplant lymphoproliferative disorder, and BKAN: BKV-associated nephropathy.
