Dysphagia-Specific Instrument Based on Item Response Theory and International Classification of Functioning, Disability and Health.
Article in Dysphagia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study aimed to identify functional challenges faced by individuals with non-esophageal dysphagia and to offer a tool for quantitatively evaluating the person abilities within the framework of the International Classification of Functioning, Disability and Health (ICF). Additionally, this study attempted to differentiate the personal abilities of individuals with dysphagia and hierarchize item difficulties using the ICF-based Item Response Theory (IRT) modeling approach. This cross-sectional study enrolled a cohort of 150 patients with dysphagia (105 male and 45 female) from a tertiary hospital in China. Participants were assigned to evaluate the 114-item ICF dysphagia questionnaire. To further assess their swallowing capabilities, eating patterns, quality of life, and nutritional status, participants underwent a battery of five additional scales. The ICF qualifiers underwent data shaping including dichotomization and missing value imputation, Mokken scale analysis (MSA) for checking unidimensionality, local independence, monotonicity, and invariant item ordering (IIO), and parametric IRT modeling for identifying an optimal model from the 1-parametric logistic model (1PLM), 2PLM, 3PLM, and 4PLM. Finally, we tested the robustness of the optimal model via Monte Carlo simulation and illustrated the usefulness of the model by its person-item map. The 1PLM emerged as the optimal model with a total of 50 ICF items (12 'd-Activities and Participation', 33 'b-Body Functions', and 5 'e-environmental' items). The final scale presented strong reliability with Cronbach's Alpha = 0.967. Furthermore, the scale showed good validity with a significant positive correlation (p < 0.001,
