  • Some theoretical thoughts when using a composite endpoint to prove the efficacy of a treatment 

    Gómez Melis, Guadalupe (2011)
    Text en actes de congrés
    Accés obert
    This paper discusses, following Gómez and Lagakos (2011) methodology, to what extent is there a gain in efficiency from adding a component event to a relevant endpoint when the treatment effect on this component is not as ...
