Nutrition-associated health levels in cancer patients based on the ICF: an expanded study of 300 cases.
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: Early assessment of nutrition-associated health levels in patients with cancer-encompassing functioning, activities, and participation-is increasingly recognized as essential for nutrition assessment and cancer rehabilitation. Using a combined approach of item response theory (IRT) and graph modeling, our previous study developed a 32-item two-parameter logistic model (2PLM) for assessing the nutrition-associated health levels of cancer patients. By expanding the sample size and updating the methods, this study aimed to refine and extend the previous findings. Methods: This study collected International Classification of Functioning, Disability, and Health (ICF) data from 300 cancer patients via a maximum variation sampling strategy, including 200 newly recruited patients and 100 from our previous study. Person abilities ( Results: The study constructed a 43-item three-parameter logistic model (3PLM) with high reliability (Cronbach's Conclusion: The study established a 43-item 3PLM for assessing nutrition-associated health levels in cancer patients and estimated both item parameters and the benefit index. By incorporating a larger sample size and updated analytical methods, the study extended prior findings and supports the utility of this integrated approach for nutritional assessment and cancer rehabilitation.
