Kaplan–Meier survival curves modelling freedom from CMV reactivation from M1 to M12 according to the result of the QF-CMV at M1. The results are presented for the manufacturer’s QF-Ag cut-off (A), the optimal QF-Ag cut-off determined by ROC curves (B), the manufacturer’s QF-Mg cut-off (C), and the optimal QF-Mg cut-off determined by ROC curves (D). Solid lines indicate QF-CMV results above the cut-off while dotted lines indicate QF-CMV results below the cut-off. HR, hazard ratio and CI, confidence interval.
