A network analysis of symptom clusters and core symptoms in colorectal cancer patients undergoing postoperative chemotherapy.

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: To identify symptom clusters in patients after colorectal cancer surgery upon completion of six cycles of chemotherapy and to determine core symptoms using network analysis, thereby providing evidence for developing precise symptom management strategies. Methods: A cross-sectional study was conducted. A convenience sample of 211 patients who had completed six cycles of chemotherapy after colorectal cancer surgery was recruited from two tertiary hospitals between February and October 2025. Participants were assessed using the MD Anderson Symptom Inventory for Gastrointestinal Cancer (MDASI-GI). Symptom clusters were extracted via exploratory factor analysis, and a symptom network was constructed using R software to identify core symptoms. Results: Three symptom clusters were identified: gastrointestinal-psychological, neurotoxicity, and CRC-specific. Network analysis revealed that "Poor appetite" had the highest node strength ( Conclusion: Poor appetite and nausea are key symptoms in the symptom network of colorectal cancer patients after surgery and chemotherapy. In clinical practice, giving priority to managing these two core symptoms, while routinely addressing fatigue as a high-frequency concern, may improve patients' overall symptom experience more effectively and enable more focused care.
