Dysphagia in progressive supranuclear palsy: A scoping review.
Article in Clinical parkinsonism & related disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Introduction: One of the most prevalent types of atypical parkinsonian syndrome is progressive supranuclear palsy (PSP). PSP is associated with early onset of dysphagia which can result in malnutrition, dehydration, and aspiration pneumonia, affecting quality of life and increasing mortality rate. To date, research describing dysphagia in PSP and its impact is scant. Methods: The objective of this scoping review is to determine the characteristics of dysphagia in PSP, differences in dysphagia presentation according to PSP subtype, principal methods used for identifying and diagnosing dysphagia and the impact dysphagia has on quality of life in individuals with PSP. This review was conducted in accordance with the JBI methodology. Six electronic databases were searched. Results: Of the 20 studies included, the most frequently reported characteristics of dysphagia were oral preparatory and oral phase difficulties. A variety of methods were used to identify and diagnose dysphagia including instrumental assessment (65%), patient reported scales (45%) and clinical swallow evaluation (20%). The most used instrumental assessment was videofluoroscopy (46%). Limited data was available describing characteristics of dysphagia according to the subtype of PSP. The impact that dysphagia has on quality of life was assessed in only one study. Conclusion: A range of assessment methods are used to identify and diagnose dysphagia in patients with PSP. Further research is needed to investigate if particular characteristics are associated with certain PSP subtypes. Future studies should also measure the impact that dysphagia has on quality of life in this population.
