Prevalence, incidence, and characteristics of dysphagia in those with unilateral vocal fold paralysis.
Article in The Laryngoscope, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
objectives/hypothesisThe purpose of this study was to investigate the impact of dysphagia definition on the incidence and overall prevalence of dysphagia in patients with unilateral vocal fold paralysis (UVP) stratified by etiology. STUDY
designRetrospective medical chart review.
methodsData was collected from the records of individuals diagnosed with UVP from 2013 to 2018, including patient demographics, dysphagia questionnaire total scores, clinical evaluation dysphagia symptoms, and instrumental swallow assessment outcomes. The annual incidence and overall prevalence of dysphagia were calculated by etiology as counts and percentages across five operational definitions of dysphagia.
resultsA total of 415 individuals met inclusion criteria for the study. Annual prevalence estimates ranged from 19% to 55%, depending on the definition of dysphagia used. The highest prevalence of dysphagia occurred when defined by symptoms or signs identified by the clinician (55%). The lowest prevalence of dysphagia occurred using a definition of abnormal swallowing function documented during instrumental assessment (19%). Dysphagia questionnaire scores were more frequently abnormal in those with iatrogenic than idiopathic etiology of UVP (adjusted P = 0.014). Rate of instrumental assessment and documentation of aspiration was highest for central UVP etiology (33%). On average, pneumonia was rare (6%) irrespective of UVP etiology.
conclusionUp to 55% of patients diagnosed with UVP complained of dysphagia, but only 21% had dysphagia symptoms severe enough to prompt instrumental assessment. Incidence and severity of dysphagia varied depending on UVP etiologic category as well as dysphagia definition. The etiology of UVP may impact dysphagia risk and severity in this population and warrants further investigation. LEVEL OF EVIDENCE: IV Laryngoscope, 130:2397-2404, 2020.
