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
purposeGastrointestinal cancers represent a significant global health burden, particularly in East Asia where incidence and mortality rates remain high. Although chemotherapy is a primary treatment strategy, its adverse effects often undermine treatment adherence and patient well-being. This study aimed to examine the psychosocial determinants of self-management behaviors in gastrointestinal cancer patients undergoing chemotherapy by applying a structural equation modeling (SEM) approach.
methodsA cross-sectional study was conducted among 753 gastrointestinal cancer patients receiving chemotherapy at eight tertiary hospitals in China. Participants completed validated instruments assessing self-management behaviors, self-efficacy, medical coping strategies, perceived social support, and psychological distress. Structural equation modeling was used to investigate the direct, indirect, and mediating effects among the variables.
resultsThe SEM analysis revealed that self-efficacy had both a direct and indirect positive effect on self-management behaviors, mediated by adaptive coping strategies. Perceived social support was significantly associated with increased self-efficacy and adaptive coping, while psychological distress negatively influenced self-management, primarily through reduced self-efficacy and increased maladaptive coping. The final model demonstrated good fit indices (CFI = 0.950, TLI = 0.933, RMSEA = 0.065), supporting the hypothesized relationships.
conclusionsSelf-management in gastrointestinal cancer patients undergoing chemotherapy is influenced by a complex interplay of psychosocial factors. Interventions that target self-efficacy enhancement, encourage adaptive coping, and strengthen social support systems may be critical to improving treatment adherence and patient outcomes.
