Nutrition impact symptoms as prognostic indicators in gastric cancer: the role of quality of life and survival outcomes.
Article in BMC cancer, 2025. 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
backgroundNutrition impact symptoms (NIS) are common among cancer patients and influence prognosis. This study aimed to investigate the prognostic significance of NIS in gastric cancer patients using data from the Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) database.
methodsWe conducted a retrospective cohort study using data from 2,673 adult patients with confirmed gastric cancer enrolled in the INSCOC database between January 2013 to February 2020. NIS, including appetite loss, vomiting, dysphagia, and early satiety, were assessed using the Patient-Generated Subjective Global Assessment (PG-SGA). Overall survival (OS) was the primary outcome, while quality of life (QoL) was the secondary outcome. Statistical analyses included Kaplan-Meier survival analysis, Cox proportional hazards regression, and propensity score matching (PSM) to reduce confounding.
resultsPatients with NIS had significantly worse OS compared to those without (median OS: 74.1 vs. 81.3 months, p < 0.001). In multivariate analysis, NIS was an independent predictor of mortality (HR: 1.28, 95% CI: 1.11-1.48, p = 0.001). Vomiting and dysphagia were particularly associated with increased mortality (HR: 1.22, p = 0.038 and HR: 1.80, p < 0.001, respectively). Interaction analysis revealed that the prognostic impact of NIS was influenced by chemotherapy (P for interaction = 0.002). NIS was also strongly associated with severe malnutrition. Sensitivity analysis confirmed the robustness of these findings, even after excluding short-term mortalities within 180 days.
conclusionsNIS are significant independent predictors of poor prognosis in gastric cancer patients, contributing to malnutrition and reduced survival. These findings highlight the importance of early symptom recognition and nutritional intervention to potentially improve outcomes for gastric cancer patients.
