Explore the Overall Benefit Index and its correlation with item difficulty among dysphagia-related syndromes in the ICF framework.

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
backgroundIndividuals with dysphagia typically experience multiple co-occurring symptoms, whose interrelationships can vary in strength. The significance and impact of each symptom within dysphagia also differ. However, the intricate web of connections among these symptoms remains poorly understood, making it challenging to assess the importance of individual symptoms from a relational perspective.
aimThe aim of this study was to: 1) construct a correlation map that identifies the risk associations within dysphagia-related syndromes; and 2) rank syndromes according to the Overall Benefit Index (OBI) of a specific functional intervention, which varies in their impact on the overall functional status.
designThis study has a cross-sectional design.
settingThe setting of this study was a tertiary hospital in Hunan Province, China. POPULATION: Population considered in this study included patients with non-esophageal dysphagia.
methodsAdopting convenience sampling, we recruited 150 patients with dysphagia to assess their health-related quality of life through the dysphagia-specific International Classification of Functioning, Disability and Health (ICF) Scale. A network structure of 50 second-level or third-level ICF categories was investigated by the Ising model. The Bayesian model was applied to determine the probability of the existence of the connection among ICF functional categories.
resultsThe resulting network consisted of 50 nodes and 64 connections. 48 functional categories demonstrated a significant OBI, with "d9102 Ceremonies" (OBI=1.00) achieving the highest OBI. "d9204 Hobbies" (OBI=0.862), and "d9205 Socializing" (OBI=0.847) were another top two categories with the 2
conclusionsThe Ising model is a powerful tool that can assist rehabilitation clinicians in better understanding the complex functional network and guide specific rehabilitation interventions for patients with dysphagia. CLINICAL REHABILITATION IMPACT: Cooperating the item difficulties from the Item Response Theory (IRT) into the OBI from the Ising model could guide individualized clinical decisions based on item difficulties and importance.
