Association Between Masticatory Difficulty and Chronic Cough in a Korean Population.
Article in International dental journal, 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
objectiveChronic cough, a common outpatient symptom, has various aetiologies, including upper airway cough syndrome, asthma, and gastroesophagoeal reflux. The potential link between dental issues and respiratory diseases has recently garnered attention. This study aims to investigate the association between masticatory difficulty and chronic cough using data from the 2011-2015 Korean National Health and Nutrition Examination Survey (KNHANES).
methodsAnalysis included 9706 individuals from KNHANES. Participants self-reported masticatory function and chronic cough. Covariates included age, sex, underlying diseases, socioeconomic status, lifestyle factors, and laboratory markers. Binary logistic regression analysed odds ratios for chronic cough covariates. Multiple logistic regression assessed adjusted odds ratios for masticatory difficulty.
resultsMasticatory difficulty prevalence was 32.2%, with chronic cough higher in this group (4.8%) than in the group without masticatory difficulty (3.0%). After adjusting for socioeconomic status, lifestyle factors, and laboratory markers, masticatory difficulty was significantly associated with greater chronic cough prevalence (odds ratio, 1.137; 95% confidence interval, 1.134-1.140).
conclusionsMasticatory difficulty was linked with an elevated chronic cough risk in Korean healthy adults. Further research, including prospective studies and detailed investigations into gastroesophagoeal reflux disease and microbiological studies, is warranted to elucidate the impact of mastication on respiratory health. As masticatory difficulty may serve as a clinical indicator for chronic cough interdisciplinary collaboration between dental and respiratory health professionals can facilitate early intervention and enhance patient care.
