|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Overall survival is defined as the time from the date of randomization to death from any cause. Patients will be followed until their date of death or until final database closure. Patients who are lost-to-follow-up or alive at the time of analysis will be censored at the time they were last known alive. |
La SG se define como el tiempo transcurrido entre la fecha de aleatorización y la muerte por cualquier causa. Se someterá a seguimiento a las pacientes hasta la fecha de la muerte o hasta el cierre definitivo de la base de datos. En las pacientes con las que se haya perdido el contacto durante el seguimiento o que estén vivas en el momento del análisis se censurarán los datos en la última fecha en que se tenga conocimiento de que estaban vivas. |
