| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To assess the efficacy of reduced duration prophylaxis followed by immuno-guided prophylaxis to prevent cytomegalovirus disease. |  
| Evaluar la eficacia de la profilaxis de duración reducida seguida de la profilaxis inmunoguiada para evitar la enfermedad por citomegalovirus. |  | 
| E.2.2 | Secondary objectives of the trial | 
| In those subjects recruited within the experimental arm who develop citomegalovirus disease despite receiving the immuno-guided prophylaxis based on QF-reactive (cut-off point of 0.2 UI/mL), it will be assessed if a different cut-off point might predict the protection against the disease with greater reliability. |  
| En aquellos pacientes del brazo experimental en los que, utilizando la profilaxis inmunoguiada basada en QF-reactivo (cut-off 0.2 UI/mL), el paciente desarrolle enfermedad por citomegalovirus, un objetivo secundario será valorar si un punto de corte diferente podría predecir con mayor fiabilidad protección frente a la enfermedad. |  |
