Patient Information and Surgery Decisions: A Discrete Choice Experiment.
Article in Health economics, 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
Surgical treatments are offered more widely than ever before, increasingly to older and high-risk patients. However, it is unclear whether patients making surgical decisions are fully informed about the risks of surgery and the available non-surgical treatments. Especially for high-risk patients, unrecognized elevated post-surgery risks may make non-surgical treatments particularly relevant. In this paper, we study the role of information provision and the availability of non-surgical treatments for high-risk patients considering hip replacement surgery in the UK. We develop a discrete choice model of incorrect beliefs about post-surgery outcomes and limited availability of non-surgical treatments, which we estimate using an online choice experiment. In the experiment, participants take the perspective of a hypothetical high-risk patient; we elicit their beliefs about post-surgery outcomes and randomize additional information about these outcomes and the availability of physiotherapy. We find that beliefs differ systematically from predicted post-surgery outcomes and that the provision of additional information has heterogeneous effects on belief accuracy. We show that excluding physiotherapy from the available treatments accounts for four-fifths of the participants' total welfare loss, while incorrect beliefs about post-surgery outcomes account for the remainder. We find evidence that education is a strong predictor of welfare loss from incorrect beliefs.
