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 is a key component of public health because it is related to quality of life, chronic disease management, and trust in health services, yet it must be measured with reliable instruments. Aim: To evaluate the validity and reliability of the Health Literacy Survey European Questionnaire's short version (HLS-EU-Q16) in Peruvian adults and to analyze health literacy according to sociodemographic variables. Methods: A cross-sectional psychometric validation study was conducted with 438 participants aged 18 to 80 years using convenience sampling. The culturally adapted HLS-EU-Q16 was administered online; its psychometric properties were analyzed using confirmatory factor analysis and reliability coefficients. Differences in literacy according to sociodemographic characteristics were evaluated using ANOVA and Pearson's correlations. Results: Confirmatory factor analysis confirmed the three-dimensional structure (health care, disease prevention, and health promotion) with excellent fit indices (CFI = 0.99, TLI = 0.99, RMSEA = 0.02, SRMR = 0.04). Internal consistency was high (α = 0.95; ω = 0.96). Significant differences in health literacy were found according to region (coast > highlands, Conclusion: The HLS-EU-Q16 demonstrates excellent validity and reliability for assessing health literacy in Peru. Significant health-literacy inequalities were identified, influenced by education, income, and access to services. These findings highlight the need for targeted strategies to improve health literacy and reduce disparities in access to and use of health information.
