Profiling the Swallowing Safety and Efficiency of Patients Presenting With Congestive Heart Failure.
Article in Laryngoscope investigative otolaryngology, 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
Purpose: Existing literature on dysphagia in patients with congestive heart failure (CHF) largely relies on patient-reported outcomes with limited instrumental data. This study aimed to objectively profile swallowing function in CHF patients using videofluroscopic swallow studies (VFSS) analyzed with the ASPEKT (Analysis of Swallowing Physiology: Events, Kinematics, and Timing) method. Methods: We conducted a retrospective study of patients admitted with CHF at St. Michael's Hospital (2021-2023). VFSS of liquid boluses was rated with penetration-aspiration scale (PAS) and ASPEKT pixel-based measures by blinded raters. Logistic regression models identified predictors of swallowing safety and efficiency. Results: Twenty-five patients met inclusion criteria. Atypical swallowing safety was observed in 67% of patients with HFpEF and in 90% of patients with HFrEF ( Conclusion: CHF may impair swallowing safety and efficiency, potentially through mechanisms similar to other pulmonary conditions. Prospective studies incorporating respiratory monitoring and stratifying by CHF severity are needed to clarify physiologic pathways and clinical risks.
