Health beliefs and quality of life in patients with gastric cancer: the chain mediating role of nutritional behaviors and nutritional status.
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Patients with gastric cancer often have reduced quality of life (QoL). This study aimed to examine whether nutritional behaviors and nutritional status serially mediate the association between health beliefs and QoL among patients with gastric cancer. Methods: This cross-sectional study included 274 patients with gastric cancer. Health beliefs, QoL, nutritional behaviors, and nutritional status were measured using validated instruments. Pearson correlation analysis was performed to examine bivariate relationships. Serial mediation analysis was conducted using structural equation modeling with bootstrap resampling (5,000 samples). Results: Health beliefs were positively correlated with QoL ( Conclusion: Health beliefs are positively associated with QoL in patients with gastric cancer, with evidence of independent and serial mediation by nutritional behaviors and nutritional status. These findings are compatible with the hypothesized theoretical model and support the development of theory-driven interventions for future testing in prospective studies.
