Malnutrition-related symptom clusters and quality of life in nasopharyngeal carcinoma patients during radiotherapy: a network analysis.
Article in BMC cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTo identify symptom clusters (SCs) of nasopharyngeal carcinoma (NPC) patients during radiotherapy and examine the relative importance of specific symptoms in relation to quality of life (QoL).
methodsThis cross-sectional study recruited non-metastatic NPC patients undergoing radiotherapy at Sun Yat-sen University Cancer Center (August 23-24, 2023). Acute toxicities, malnutrition, and QoL were assessed using the patient-reported outcome version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE), modified Patient-Generated Subjective Global Assessment (mPG-SGA), and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck 35 (EORTC QLQ-H&N35), respectively. Exploratory factor analysis and network analysis were used to identify SCs and characterize central and bridge symptoms. Multivariable logistic regression was conducted to explore factors associated with QoL.
resultsA total of 437 eligible patients (73.46% male; median [IQR] age, 47 [38-55]) were included. Most patients reported ≥ 5 acute toxicities (88.56%) and severe malnutrition (75.06%). Three SCs (corresponding central symptoms) were identified from 18 prevalent items of PRO-CTCAE: general SC (anxiety), head-neck SC (dysphagia), and gastrointestinal SC (nausea). Malnutrition showed high bridge connectivity across SCs. The network remained relatively stable across early and late radiotherapy phases. Among multiple variables examined, the head-neck SC showed the strongest association with poorer QoL (β = 1.805, P < 0.001).
conclusionsNPC patients experience multiple co-occurring symptoms that organize into distinct clusters associated with QoL throughout radiotherapy. Dysphagia in head-neck SC and malnutrition deserve to be priorities for early management to relieve the global network burdens.
