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: This study was conducted to examine the associations of nutrition literacy, healthy eating attitudes, and sustainable and healthy eating behaviors with food insecurity among young adults, and to assess the mediating role of healthy eating attitudes in the relationship between nutrition literacy and sustainable and healthy eating behaviors. Methods: This cross-sectional study included 600 young adults aged 18-25 years from Siirt and Gaziantep, Türkiye. Data were collected using a sociodemographic form, Turkish Short Nutrition Literacy Scale for Young Adults (S-NutLit-Tr), Attitude Scale for Healthy Nutrition (ASHN), the Sustainable and Healthy Eating Behaviors Scale (SHE Behaviors), and the Food Insecurity Experience Scale (FIES). Group differences, predictors of SHE Behaviors, and the indirect association through healthy eating attitudes were examined using Kruskal-Wallis tests, multiple linear regression, and path analysis, respectively. Results: The mean age of the participants was 20.56 ± 1.87 years, and 50.7% were female. While 50.7% of the participants were food secure, moderate food insecurity was identified in 23.8% and severe food insecurity in 25.5%. Significant differences were observed across FIES groups in total S-NutLit-Tr and ASHN scores (Kruskal-Wallis H(2) = 8.752, Conclusion: Among young adults, nutrition literacy and positive attitudes toward healthy eating are positively associated with sustainable and healthy eating behaviors. Healthy eating attitudes represented a small but statistically significant indirect pathway in this association. These findings suggest that interventions targeting young adults may benefit from addressing both the improvement of nutrition literacy and the strengthening of healthy eating attitudes.
