Viral dynamics of BKV, CMV, and EBV during the first post-transplantation year. Prevalence and viral load levels for BKV (blue), CMV (red), and EBV (green) are plotted for the eight visits of the study. The size of the points is a function of the prevalence of positive measurements (viral load over detection level). The height of the points represents the median viral load (copies·mL⁻¹) of positive measurements; the bars indicate the interquartile range. Asterisks indicate a significant difference calculated with the Mann-Whitney test (* p < 0·05; ** p < 0·01; *** p < 0·001) in viral load (only samples with detectable viral load) for each virus.
