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 AND
objectivesUndernutrition is prevalent among patients with cancer and may be associated with survival. The Patient-Generated Subjective Global Assessment (PG-SGA) is a widely recognised scale for the nutritional assessment of patients with cancer. The relationship between undernutrition, as defined by the PG-SGA, and cancer prognosis has been somewhat controversial, and this meta-analysis sought to clarify this. This meta-analysis was performed to elucidate the association between undernutrition, as defined by the PG-SGA, and survival outcomes in patients with cancer. METHODS AND STUDY
designStudies that investigated the association between undernutrition, defined by the PG-SGA, and survival outcomes in patients with cancer were included, and data were retrieved from PubMed, EMBASE, the Cochrane Library, and Web of Science until October 2023.
resultsA total of 18 prospective and 14 retrospective studies with 27120 cancer patients were identified in this analysis. All studies had high methodological quality, with an average score of 7.66. The results showed that undernutrition, as defined by the PG-SGA, was significantly correlated with worse overall survival (Hazard Ratio (HR) = 1.99, 95% Confidence Interval (CI): 1.62-2.45). Subgroup analyses further confirmed that the pooled HR was 1.64 (95% CI: 1.26-2.13) for moderate undernutrition, which increased gradually in cases of severe undernutrition (HR = 2.65, 95% CI: 2.45-2.87). The degree of undernutrition might be the source of the heterogeneity (p value for the test of subgroup differences was < 0.001). Sensitivity analyses confirmed the robustness and credibility of this meta-analysis.
conclusionsThese results under-score the significant association between undernutrition, as defined by the PG-SGA, and reduced overall survival in patients with cancer. Detection of nutritional status using the PG-SGA may be beneficial for improving survival in patients with cancer.
