Correlation study of discomfort symptom clusters and self-management in patients with knee osteoarthritis: a cross-sectional study.
Article in BMC geriatrics, 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
backgroundThis study aimed to explore the relationship between knee discomfort symptom clusters and self-management in old patients with knee osteoarthritis(KOA), providing a basis for clinical improvement of patient symptoms and self-management.
methodsStratified multistage random sampling was adopted to select KOA patients in Changsha and Zhangjiajie, Hunan Province, and their discomfort symptoms and self-management were investigated using the Self-assessment of Knee Discomfort Symptoms of Middle-aged and Older People Questionnaire and the Self-Management of Knee Discomfort Questionnaire for Middle-aged and Older People. Self-management of the survey included symptom management, daily life management, emotion management, and information management. Exploratory factor analysis was used to identify symptom clusters. Pearson correlation analysis and stratified multiple linear regression analysis were used to explore the relationship between discomfort symptom clusters and self-management.
results651 old patients participated in the study. Mean participant self-management entry score (2.53 ± 0.67), 74.8% of patients had low self-management. Of the 21 knee discomfort symptom weights, 12 symptoms with > 80% incidence were selected to form 3 symptom clusters: “Pain-Related Self-Perceived Symptom Cluster” “Limited joint movement symptom cluster”“ Muscle-related self-perception symptom clusters”. All symptom clusters were positively correlated with self-management in KOA patients(r = 0.129–0.382, P < 0.05). BMI, pain-related self-perceived symptom cluster, limited joint movement symptom cluster and muscle-related self-perception symptom clusters significantly associated self-management (P < 0.01).
conclusionOlder patients with knee osteoarthritis exhibit suboptimal self-management capabilities, which are significantly associated by BMI and specific symptom clusters (pain, movement, and muscle perception). Management strategies focusing on these symptom clusters, rather than isolated symptoms, may provide a more effective pathway to improve patient self-management and clinical outcomes. Future research should continue to explore the network distribution of discomfort symptoms and understand the micro-interactions between symptoms and symptom clusters.
