Kaplan–Meier survival curves modelling freedom from CMV reactivation through day + 360 post-transplant according to the result of TTV load at D0 or M1. The results are presented according to the TTV cut-off of 3.45 log₁₀ copies/ml at D0 (A), the TTV cut-off of 3.45 log₁₀ copies/ml at M1 (B), the optimal TTV cut-off at D0 determined by ROC curves (3.78 log₁₀ copies/ml) (C), and the optimal TTV cut-off at M1 as defined by ROC curves (4.23 log₁₀ copies/ml) (D). Dotted lines indicate TTV load above the cut-off while solid lines indicate TTV load below the cut-off. HR, hazard ratio and CI, confidence interval.
