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
Objectives: To test the relationship between nutritional literacy, self-efficacy, family support and cancer anorexic behavior among patients with gastrointestinal cancer undergoing chemotherapy. And examine the moderating role of family support on the relationship between nutritional literacy and self-efficacy. Methods: Using convenience sampling, 248 patients with gastrointestinal cancer undergoing chemotherapy were recruited from the Oncology Center of a Grade A Level 3 general hospital in Henan Province, China, between June and November 2025. Data analysis was performed by SPSS 27.0, while PROCESS macro v5.0 was used to test the moderated mediation model. Results: Nutritional literacy mediated by self-efficacy was positively associated with anorexic behavior score ( Conclusions: This study found that nutritional literacy among patients with gastrointestinal cancer is directly associated with cancer anorexic behavior and indirectly associated with it through self-efficacy. Furthermore, family support moderates the relationship between nutritional literacy and self-efficacy. Moving forward, interventions should be implemented on three fronts-improving patients' nutritional literacy, strengthening their sense of self-efficacy, and enhancing family support systems-to alleviate cancer-related anorexia, improve nutritional status, and enhance quality of life.
