Improving Power of the Win Ratio Analysis through Distance-based Weights.
Article in Statistics in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The win ratio method, used to analyze composite endpoints in clinical trials, has gained substantial popularity in recent years because of its ability to prioritize components of the composite outcome. Despite gaining popularity and being extended to solve some of its issues, little work has been done to incorporate covariate information into the win ratio. In this article, we extend the win ratio method by incorporating weights to each win or loss based on the distance between the compared pair using their covariate values. This approach aims to improve the power of the original win ratio when the covariates used for computing the weights are associated with the components of the composite outcome. Through detailed simulation studies and real data analyses, we demonstrate the utility of our proposed method. In general, our simulation studies indicate that the proposed method is more powerful when covariates used to calculate the weights are associated with the outcomes, and it performs similarly to the original method when there is no such association.
