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
Introduction: Chronic illnesses such as inflammatory bowel disease (IBD) require continuous self-management, often under emotionally and physically taxing conditions. While health literacy and health self-efficacy are known to support disease adaptation, their combined role in psychosomatic functioning, especially under varying levels of depression, remains underexplored. This study examined how health literacy, health self-efficacy, and depressive symptoms influence symptom severity and life satisfaction in patients with IBD. Methods: A cross-sectional survey of 393 patients with IBD (60.7% with Crohn's disease; 56% female; mean age = 40.75) was conducted at a gastroenterology outpatient clinic in Hungary. Standardized questionnaires assessed health literacy, health self-efficacy, depression, symptom severity, and satisfaction with life. Structural equation modeling was used to test a mediation model. Multigroup analyses explored the stability of the model across subgroups defined by depressive symptom levels, disease status (relapse vs. remission), and types of diseases. Results: Critical health literacy predicted higher health self-efficacy, which was associated with lower symptom severity and, in turn, greater life satisfaction. This indirect pathway remained significant after controlling demographic variables. Multigroup analyses showed that these relationships were stronger among patients in relapse and those with elevated depression, suggesting increased psychological sensitivity in these subgroups. No difference was found between types of disease. Discussion: The findings underscore the importance of critical health literacy and health self-efficacy as interconnected psychological resources in chronic illness self-management. Strengthening these capacities may reduce symptom burden and enhance well-being, particularly in times of relapse and periods of psychological vulnerability. The results support a shift toward integrated, psychosocially informed care models for IBD.
