Low handgrip strength, GLIM-defined malnutrition, or their coexistence: which has the greatest impact on health-related quality of life in patients with cancer?
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
backgroundMalnutrition and reduced muscle strength are prevalent among patients with cancer and are both linked to impaired health-related quality of life (HRQoL). Although the individual impacts of these conditions are well documented, their combined effect remains insufficiently explored. This study aimed to examine how coexisting GLIM-defined malnutrition and low handgrip strength (HGS) affect HRQoL.
methodsThis-cross-sectional study (November 2024-June 2025) involved adult patients with cancer undergoing clinical treatment. Sociodemographic, clinical, lifestyle, and anthropometric information was collected. Malnutrition was defined according to the Global Leadership Initiative on Malnutrition (GLIM) criteria, and low HGS was used as a marker of reduced muscle strength. Coexistence was characterized by the simultaneous presence of malnutrition and low HGS. HRQoL was evaluated using the EORTC QLQ-C30 (0–100 scores), where higher functional scores indicate better HRQoL and higher symptom scores indicate greater symptom burden. Continuous variables were summarized as medians and interquartile ranges, and group differences were tested with nonparametric methods. Adjusted associations were examined using univariate general linear models, expressed as adjusted mean differences (Δ) and effect sizes (partial eta-squared, [Formula: see text]). Statistical significance was set at p < 0.05.
resultsAfter adjustment, low HGS showed significant and stronger associations with all functional scales and most symptom scales, whereas GLIM-defined malnutrition alone remained associated only with appetite loss. The coexistence of malnutrition and low HGS was associated with poorer physical (Δ = -35.1; p = 0.002; [Formula: see text] = 0.240), role (Δ = -40.3; p = 0.014; [Formula: see text]= 0.216), and emotional functioning (Δ = -27.7; p = 0.044; [Formula: see text] = 0.125). Coexistence was also associated with higher levels of fatigue (Δ = 37.9; p < 0.01; [Formula: see text]= 0.201), nausea and vomiting (Δ = 29.5; p ≤ 0.020; [Formula: see text]= 0.209), pain (Δ = 36.0; p = 0.027; [Formula: see text]= 0.134), dyspnea (Δ = 18.0; p = 0.042; [Formula: see text]= 0.132), and appetite loss (Δ = 39.6; p = 0.015; [Formula: see text]= 0.132).
conclusionsThe coexistence of GLIM-defined malnutrition and low HGS is associated with poorer HRQoL in patients with cancer, with low handgrip strength being particularly relevant to HRQoL impairment.
