Digital trust in medical tourism portals: multiple pathways to consumer confidence.
Article in Frontiers in digital health, 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
This study examines how consumer confidence is configurationally constructed in medical tourism portals using fuzzy-set Qualitative Comparative Analysis (fsQCA). Drawing on established theoretical perspectives, seven antecedent conditions are analyzed: Information Quality, Trust and Credibility Signals, Platform Quality and Usability, Security and Privacy Protection, Risk Perception Reduction, Communication and Responsiveness, and Governance and Ethical Transparency. Survey data from 163 portal users were analyzed across 128 possible configurations, applying a consistency threshold of 0.85 and a frequency cutoff of 3. The necessary condition analysis indicates that no single factor meets the 0.90 consistency threshold, suggesting the absence of a dominant driver of consumer confidence. Sufficiency analysis identifies four distinct equifinal pathways explaining 60% of high-confidence cases, with an overall solution consistency of 0.77. The findings highlight compensatory and asymmetric mechanisms in which combinations of informational, technological, and institutional factors jointly shape consumer confidence in digital healthcare platforms.
