Overcoming Barriers to Warfarin Patient Self-Management (PSM) in the US Healthcare System: Implementation Trial Study Protocol.
Article in medRxiv : the preprint server for health sciences, 2025. 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
Introduction: Warfarin is a narrow therapeutic index drug that requires frequent monitoring using the international normalized ratio (INR). Current clinic-based INR monitoring models lead to suboptimal warfarin management. Warfarin patient self-management (PSM) has consistently demonstrated superior efficacy compared to clinic-based management but is virtually unused in the US healthcare system. The objective of this study is to implement PSM in the US healthcare system using strategies developed to overcome previously identified barriers associated with PSM underutilization as well as potential PSM facilitators. Methods and analysis: We aim to implement PSM with 150 adult patients at four sites using strategies developed to address barriers to PSM specific to the US healthcare system. Implementation strategies will be guided by the Consolidated Framework for Implementation Research and the Quality Implementation Framework supported by Rapid Cycle Research Methodology. A type III hybrid implementation-effectiveness study design will be used to assess PSM implementation strategy outcomes while also gathering information on PSM clinical outcomes centered on the five elements of the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance). This study will be approved by the ethics boards at all participating sites. Discussion: We plan to disseminate the results of this research program examining the feasibility of PSM in US anticoagulation management services in scientific journals and conferences, as well as making elements of the PSM implementation toolkit publicly and freely available.
