Provider Preferences About a Polypill for Heart Failure With Reduced Ejection Fraction: Development of a Multicenter Physician Survey Containing a Discrete Choice Experiment.
Article in Journal of cardiac failure - intersections, 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
Background: Guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) reduces mortality rates but remains widely underused. A polypill for HFrEF has been proposed as an implementation strategy to improve GDMT delivery, but little is known about physicians' preferences in the design of HFrEF polypills. Discrete choice experiments (DCEs), in which survey respondents choose among hypothetical products, are a powerful tool in health economics research and can lend insight into key tradeoffs in HFrEF polypill design. However, the process of designing DCEs is complex and often poorly reported. Methods: We developed a survey instrument, including a DCE, through a 5-stage mixed-methods process including (1) literature review; (2) physician interviews and surveys; (3) attribute generation; (4) expert review; and (5) pilot testing. We applied a D-efficient design approach using a multinomial logic model to determine the number of choice tasks for the DCE. Results: We designed a DCE with 4 attributes: HFrEF polypill out-of-pocket cost, inclusion of an angiotensin converting enzyme inhibitor, angiotensin receptor blocker, or sacubitril/valsartan, ancillary support for polypill prescribing, and pharmacy availability. The final survey will be distributed to cardiologists in academic and Veterans Administration medical centers across the United States. Conclusions: Through a rigorous multistage design process leveraging mixed methods, we developed a DCE that elicits cardiologists' preferences about HFrEF polypills and key tradeoffs in their design. Results from this DCE study will directly inform future HFrEF polypill cluster-randomized clinical trials.
