Malnutrition predicts severe complications but not survival in laryngeal cancer surgery: a propensity-matched analysis.
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
Background: The impact of preoperative malnutrition on clinical outcomes in patients undergoing laryngeal cancer surgery remains incompletely defined. This study aimed to evaluate the association between malnutrition and postoperative complications, long-term prognosis, and other clinical outcomes, and to compare the predictive performance of the GLIM criteria versus the ESPEN 2015 criteria. Methods: A retrospective analysis was conducted on prospectively maintained records of 294 laryngeal cancer patients who underwent surgical resection. Malnutrition was diagnosed according to the Global Leadership Initiative on Malnutrition (GLIM) criteria, and the ESPEN 2015 criteria were additionally applied for comparison. The cohort was chronologically divided into a training set ( Results: The prevalence of preoperative malnutrition was 25.9% (76/294) according to GLIM criteria and 13.6% (40/294) according to ESPEN criteria. Malnutrition defined by both criteria was an independent risk factor for severe POCs, and the GLIM criteria demonstrated superior predictive performance. Age >65 years, diabetes, GLIM-malnutrition, and neck dissection were identified as independent risk factors for severe complications. The nomogram constructed based on these predictors exhibited robust predictive performance, with AUC values of 0.803 in the training set and 0.812 in the validation set, along with good calibration and net clinical benefit. In terms of prognosis, the 5-year overall survival rates were 55.0% in the GLIM-malnutrition group and 60.8% in the normal nutrition group, with no significant difference ( Conclusion: Preoperative malnutrition diagnosed by GLIM criteria is highly prevalent in patients undergoing laryngeal cancer surgery and significantly increases the risk of severe complications and prolongs hospital stay. Compared with ESPEN criteria, GLIM criteria show stronger predictive performance for severe postoperative complications. However, preoperative malnutrition does not independently affect long-term overall survival.
