Win Ratio -An Intuitive and Easy-To-Interpret Composite Outcome in Medical Studies.

Abstract

In medical studies with multiple outcomes, researchers always need to make choices as to whether to use a composite outcome (after combining multiple outcomes) as their primary outcome. In this paper we review a new measurement of the treatment effect - win ratio, which can be easily used in studies with prioritized multiple outcomes. We also propose some research topics to be done in this area.
