BK viral load relationship to BK nephropathy. Legend: Dot diagrams with Receiver Operator Characteristic analysis of those without (0) and with (1) BK nephropathy of: a first positive urine BK viral load b first positive plasma BK viral load c peak urine BK viral load d peak plasma BK viral load. Viral loads are log10 copies/mL. Horizontal lines designate optimum cut-offs. Sens = sensitivity, Spec = specificity
