Prevalence of malnutrition and its prognostic impact in lung metastasis patients treated with SBRT: insights from NRI, CONUT, NRS, and PNI.
Article in Frontiers in nutrition, 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
Objective: Malnutrition is a significant and modifiable prognostic factor in patients with pulmonary metastases undergoing stereotactic body radiotherapy (SBRT). This study evaluated and compared the prognostic utility of four nutritional assessment tools-Nutritional Risk Index (NRI), Controlling Nutritional Status (CONUT), Nutritional Risk Screening 2002 (NRS), and Prognostic Nutritional Index (PNI)-to identify malnutrition patients and inform potential interventions for improving survival. Methods: In this retrospective cohort study of 185 patients with pulmonary metastases treated with SBRT, nutritional status was assessed using the NRI, CONUT, NRS, and PNI. The primary endpoint was overall survival (OS). Statistical analyses encompassed survival analysis, subgroup exploration, correlation assessment, and development of an integrated prognostic model. Results: Malnutrition prevalence varied: 65.95% (NRI), 63.78% (CONUT), 77.84% (NRS), and 79.46% (PNI) of patients had some nutritional impairment. Multivariable analysis identified CONUT (HR = 1.09) and NRI (HR = 3.99) as independent prognostic factors for OS. An integrated model combining nutritional (CONUT, NRI) and clinical variables showed superior predictive performance (C-index: 0.681) compared to any single tool. Conclusion: Malnutrition is highly prevalent and prognostic in SBRT-treated lung metastasis patients. CONUT and NRI are effective for risk stratification. The integrated model offers a superior prognostic tool, supporting the routine integration of these nutritional assessments into clinical practice to identify high-risk patients for timely intervention.
