The G8 tool for screening malnutrition before GLIM in geriatric cancer patients.
Article in BMC cancer, 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
purposeIn our study, we examined the alignment of the G8 Geriatric Screening Tool with the Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria, as well as its effectiveness in identifying malnutrition among geriatric patients with malignancies.
methodsIn a cross-sectional study, geriatric patients newly diagnosed with malignancy, who had an Eastern Cooperative Oncology Group Performance Status (ECOG-PS) score of ≤ 1 and consented to participate, were included. The Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria were employed to diagnose malnutrition. Receiver operating characteristic (ROC) curves were constructed to evaluate the diagnostic accuracy of the G8 tool, the Mini Nutritional Assessment-Short Form (MNA-SF), and the Mini Nutritional Assessment (MNA) questionnaire in identifying malnutrition.
resultsAccording to the GLIM diagnostic criteria, 79 (57%) of 138 patients had malnutrition. Muscle strength and muscle mass were significantly lower in patients with malnutrition (p = 0.022, p < 0.001, respectively). Scores of the MNA-SF, the MNA and the G8 tool area under the curve (AUC) in ROC curve analysis for malnutrition were 0.859, 0.804 and 0.829, respectively.
conclusionThis study illustrates that the G8 tool is efficacious in screening for malnutrition prior to the application of the GLIM diagnostic criteria in geriatric oncology patients.
