eHealth literacy and decisional conflict in patients with coronary heart disease: chain mediation of cyberchondria and psychological inflexibility and a latent profile analysis.

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: Coronary heart disease (CHD) is the leading cause of cardiovascular mortality worldwide, and its management requires patients to make complex, preference-sensitive treatment decisions. Decisional conflict is common in this population and adversely affects treatment adherence and outcomes, yet its association with eHealth literacy and the underlying psychological mechanisms remain unclear. Objective: This study examined the association between eHealth literacy and decisional conflict in patients with CHD, tested the chain-mediating roles of cyberchondria and psychological inflexibility, and identified latent profiles of eHealth literacy. Methods: A cross-sectional design was employed, and patients with CHD were recruited from tertiary Grade A hospitals. The survey battery comprised the eHealth Literacy Scale, the Decisional Conflict Scale, the Cyberchondria Severity Scale, the psychological inflexibility subscale of the Multidimensional Psychological Flexibility Inventory, and requisite demographic items. Results: eHealth literacy was significantly and negatively associated with decisional conflict, and this association was mediated by cyberchondria and psychological inflexibility. From a person-centered perspective, two latent subgroups of eHealth literacy were identified: a high eHealth literacy profile and a low eHealth literacy profile. One-way analysis of variance indicated that the optimal latent profiles differed significantly in decisional conflict, cyberchondria, and psychological inflexibility. Conclusion: This study not only helps identify priority targets for interventions addressing decisional conflict in patients with CHD, but also elucidates the psychological pathways through which eHealth literacy shapes treatment decision-making, thereby informing heterogeneity-informed, tailored clinical interventions.
