Cumulative incidence of CMV reactivation according to CD4⁺ and CD16⁺ reconstitution levels and presence of donor KIR 3DL1. a Patients were subdivided based on their CD4⁺ T cell count 5 weeks post-SCT. The cumulative incidence (CI) of CMV reactivation was plotted for patients with a CD4⁺ T cell count below or above the median value of 55 cells/μl. Similarly, in (b) patients were subdivided based on their CD16⁺ cell count 5 weeks post-SCT. The median value for the whole patient population was 84 cells/μl. c Patients were subdivided by the presence or not of donor inhibitory KIR 3DL1. CI of viral reactivation curves were estimated by Kaplan–Meier analysis and the comparison between the curves of the different groups was evaluated by the log-rank test
