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
Purpose: To examine factors associated with nutritional self-management behavior and their hypothesized relationships within the Information-Motivation-Behavioral Skills (IMB) framework among patients undergoing maintenance hemodialysis (MHD). Patients and Methods: This single-center cross-sectional study included a convenience sample of 215 patients undergoing MHD at a tertiary hospital in Shenzhen, China, between January and May 2026. Questionnaires assessed hemodialysis knowledge, health beliefs, social support, self-management, and nutritional self-management behavior. Pearson correlations and multiple linear regression were analyzed. Because the initially planned latent-variable structural equation model showed inadequate measurement-model fit, an observed-variable path analysis using composite scores was conducted. Indirect associations were estimated using 5000 bias-corrected bootstrap resamples. Results: The mean nutritional self-management behavior score was 86.47 ± 9.86 (scoring rate, 72.06%). In the regression model, health beliefs (β = 0.190, P = 0.003) and self-management (β = 0.365, P < 0.001) were positively associated with nutritional self-management behavior. In the path model, health beliefs had the largest coefficient for self-management (β = 0.437, P = 0.001), and self-management had the largest coefficient for nutritional self-management behavior (β = 0.380, P < 0.001). Hemodialysis knowledge, health beliefs, and social support showed significant indirect associations through self-management; the largest was for health beliefs (β = 0.166). Explained variance was 25.7% for self-management and 33.2% for nutritional self-management behavior. Conclusion: These cross-sectional associations provide preliminary evidence consistent with the hypothesized IMB framework. Longitudinal and intervention studies are needed to establish temporal relationships and evaluate potential intervention strategies.
