Article in International journal of general medicine, 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 and Objective: Malnutrition significantly contributes to the adverse prognosis of patients with chronic kidney disease (CKD). The Global Leadership Initiative on Malnutrition (GLIM) criteria were introduced to standardize malnutrition diagnosis globally. This study evaluates the diagnostic performance and agreement of the GLIM criteria compared with the Subjective Global Assessment (SGA) in non-dialysis CKD patients. Methods: In this cross-sectional study, 248 non-dialysis CKD patients (stages G1-G5) were screened using the Nutritional Risk Screening 2002 (NRS-2002). Patients with a score <3 were classified as well-nourished. Those with a score ≥3 underwent GLIM assessment incorporating phenotypic and etiologic parameters. CKD was operationalized as fulfilling the GLIM disease-burden/inflammation etiologic criterion; therefore, GLIM-based prevalence was interpreted in light of this assumption. Concurrently, all patients were assessed using SGA (the reference standard). Diagnostic agreement was evaluated using Cohen's Kappa, sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC). Multivariable logistic regression identified factors independently associated with GLIM-diagnosed malnutrition. Results: The prevalence of malnutrition was 46.8% by SGA and 49.2% by GLIM. The GLIM framework demonstrated substantial agreement with SGA (Kappa = 0.812, P < 0.001). The GLIM criteria exhibited a sensitivity of 87.9%, a specificity of 84.8%, and an AUC of 0.864 (95% CI: 0.818-0.910). Malnutrition prevalence increased progressively with advanced CKD stages (P < 0.001). Multivariable analysis revealed that advanced CKD stage, older age, and lower serum albumin were factors independently associated with GLIM-diagnosed malnutrition. Conclusion: The GLIM criteria demonstrate good diagnostic agreement with the SGA in assessing malnutrition among non-dialysis CKD patients. While GLIM provides a standardized and structured framework, longitudinal studies are required to validate its predictive value for clinical outcomes.
