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
Nutrition label use among patients with coronary heart disease (CHD) is limited. This study aims to investigate the mediating effect of dietary self-efficacy on the relationship between health literacy and nutrition label use in CHD patients. This cross-sectional study recruited 350 CHD patients using convenience sampling from two hospitals in Changsha City. Data were collected using a general information questionnaire, the Newest Vital Sign Scale, the Cardiac Diet Self-efficacy Scale, and the Nutrition Label Use Questionnaire. SPSS 25.0 was used for Pearson correlation analysis and multiple linear regression analysis, while Model 4 in the SPSS macro program PROCESS was applied for mediation effect analysis. The results indicated health literacy and dietary self-efficacy were positively and significantly correlated with nutrition label use in CHD patients (P < 0.001). Bootstrap test results demonstrated that dietary self-efficacy partially mediated the relationship between health literacy and nutrition label use, with a mediation effect of 0.184 (95% CI: 0.144-0.225), accounting for 55.42% of the total effect. In conclusion, dietary self-efficacy mediates the relationship between health literacy and nutrition label use in CHD patients. Targeted interventions that address both health literacy and dietary self-efficacy are crucial for improving nutrition label use among CHD patients.
