While 1-year OS and LFS were comparable across groups ( p < 0.2), the gap widened progressively thereafter; by 3 years, patients with CMV/EBV coreactivation showed the lowest OS (20.3%) and LFS (19.3%), with the OS difference approaching significance ( p = 0.051) and LFS already significant ( p = 0.028).
