In randomized controlled trials in oncology, changes in quality of life are usually reported together with a description of the differences considered a priori to be clinically important, but overall survival outcomes are rarely provided together with information of what constitutes a clinically meaningful threshold. In this Comment, we propose the benefits that could be derived from reporting overall survival in a similar way to quality of life.
