Trust, perceived accuracy, and continued use of patient-facing symptom monitoring applications: Cross-sectional study.
Article in Digital health. 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: Patient-facing symptom monitoring applications are increasingly used in digital health to support preliminary symptom assessment and health-related decision-making. While perceived accuracy and trust are recognized as important determinants of mHealth adoption, their joint role in shaping users' continued engagement with symptom monitoring applications remains insufficiently understood. Objective: This study examined the relationships among perceived accuracy, trust, and continued use intention of symptom monitoring applications and assessed whether trust mediates the association between perceived accuracy and continued use intention. Methods: A cross-sectional survey was conducted among 300 adult outpatients recruited from three affiliated hospitals in China. Participants evaluated a debranded symptom monitoring application scenario and completed validated measures of perceived accuracy, trust, continued use intention, and eHealth literacy. Multiple linear regression analyses were performed with adjustment for demographic and health-related covariates. Mediation analysis with bootstrap resampling was used to estimate indirect effects. Results: Perceived accuracy was positively associated with continued use intention (B=0.52, p<.001) and trust (B=0.48, p<.001). Trust was strongly associated with continued use intention (B=0.47, p<.001) and showed a larger effect size than perceived accuracy in the full model. Mediation analysis indicated that trust partially mediated the relationship between perceived accuracy and continued use intention. Findings were consistent across sensitivity and subgroup analyses. Conclusion: Perceived accuracy and trust jointly influence continued use intention of symptom monitoring applications, with trust acting as a key mechanism linking performance perceptions to sustained engagement. Promoting trust alongside technical performance may support more sustainable use of patient-facing digital health technologies.
