Prevalence of Laryngeal Abnormal Sensation in a Hospital Worker Population and its Association with Cough Hypersensitivity.
Observational study in Lung, 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
purposeCough hypersensitivity is characterized by exaggerated cough responses to mild stimuli, which is frequently associated with laryngeal abnormal sensation (LAS). However, the clinical characteristics of LAS and its prevalence in a non-clinical working population remain unclear. This study aimed to investigate the clinical characteristics and prevalence of LAS.
methodsThis cross-sectional study included 556 healthcare workers (aged 20-72) from Gamagori City Hospital, Japan. Participants completed the Newcastle Laryngeal Hypersensitivity Questionnaire (NLHQ), Hull Airway Reflux Questionnaire, and Leicester Cough Questionnaire (LCQ). LAS was defined as an NLHQ score < 17.1. Binary logistic regression was used to analyze LAS-associated factors.
resultsLAS was present in 9.5% of participants. The LAS-positive group had significantly higher prevalence of asthma (13.2% vs. 3.4%, P = 0.005), chronic rhinosinusitis (7.5% vs. 1.0%, P = 0.006), and gastroesophageal reflux disease (GERD; 11.3% vs. 1.2%, P < 0.001). Cough prevalence was significantly higher in the LAS( +) group (45.2% vs. 9.5%, P < 0.001), and quality of life was impaired, as indicated by lower LCQ scores. Multivariate analysis revealed that asthma (OR = 5.092, P = 0.002), GERD (OR = 12.397, P < 0.001), and mood swings (OR = 2.957, P = 0.003) were independent risk factors for LAS.
conclusionLAS markedly affects symptoms like cough and impairs quality of life, and is independently associated with asthma, GERD, and mood swings. It may reflect a sensory phenomenon of vagal hypersensitivity that could contribute to the pathophysiology of such chronic conditions.
