Digital Health Information Use, Trust, and Language-Related Disparities in Health Literacy in South Tyrol, Italy: Cross-Sectional Survey Study.

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: Health literacy (HL) is a crucial determinant of population health; however, disparities persist in multilingual settings. In South Tyrol, Italy, where German- and Italian-speaking populations coexist within a unified health care system, HL disparities may reflect differences in language, culture, and digital engagement. Objective: This study investigated whether the usage of digital health information mediates the relationship between language group and HL and examined informational trust and other sociodemographic factors as covariates of HL. Methods: Data were obtained from a population-based survey conducted in South Tyrol, Italy. The analytical sample comprised 1500 participants with adequate responses to the 16-item Health Literacy Survey European Union Questionnaire (HLS-EU-Q16) instrument and an identified language group. Mediation analysis was performed using PROCESS Model 4 (5000 bootstrap samples), with use of digital health information as the mediator, language group as the predictor, and HL as the outcome. Covariates included age, sex, education, self-rated health, trust in professional information sources, and trust in health information on the internet. Results: Italian-speaking participants showed significantly higher HL scores (mean 12.54, SD 3.31 vs mean 11.56, SD 3.48 on a 0-16 scale; Conclusions: Although digital engagement and online trust are related to HL, they do not explain the persistent language-based disparities in HL observed in South Tyrol. Public health strategies should prioritize strengthening critical appraisal skills, fostering trust in professional health information sources, and improving digital access to effectively address HL inequalities in multilingual populations.
