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: Employees in the petrochemical industry are exposed to numerous occupational hazards, contributing to a higher prevalence of chronic diseases. Health literacy, which reflects an individual's ability to access, understand, and use health information, is a critical factor in managing chronic diseases. However, its specific role in this workforce is not well understood. Objective: This study investigates the associations between health literacy and the prevalence and number of chronic diseases among employees in a Chinese petrochemical company. Methods: In March 2022, a cross-sectional survey collected 39,491 valid responses from employees of a large petrochemical company in Shandong Province, China. Health literacy was measured using the National Health Literacy Monitoring Questionnaire, while chronic disease prevalence and number were self-reported. Logistic and linear regression were used to examine associations between health literacy and chronic disease prevalence and count, respectively. Results: Among respondents, 72.1% reported at least one chronic disease, and 53.9% were classified as having adequate health literacy. The domain of Health-Related Skills had the lowest qualification rate (46.4%), and the dimension of Chronic Disease Prevention and Control was the lowest-scoring dimension (33.0%). Overall health literacy was not significantly associated with chronic disease prevalence but was negatively associated with the number of chronic diseases (B = -0.05, 95% CI: -0.08 - -0.02, p < 0.001). Notably, higher literacy in Chronic Disease Prevention and Control was significantly associated with both reduced prevalence (OR = 0.95, 95% CI: 0.90-1.00, p = 0.034) and fewer chronic diseases (B = -0.01, 95% CI: -0.02-0.00, p = 0.004). Conclusion: While overall health literacy was not significantly associated with chronic disease prevalence, it was negatively associated with the number of chronic diseases. Moreover, health literacy in Chronic Disease Prevention and Control showed significant associations with both lower prevalence and fewer chronic diseases.
