Tongue function and high-risk sleep-disordered breathing in youth: age-stratified associations and interactions in a Vietnamese cross-sectional study.

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
purposeTo examine associations between tongue function domains and questionnaire-based high-risk sleep-disordered breathing classification across age groups, and to explore interaction effects between functional and anatomical factors.
methodsA cross-sectional study included 1,244 participants (462 children aged 6–8 years and 782 young adults aged 18–25 years). High-risk classification was defined as meeting ≥ 1 age-appropriate threshold: Pediatric Sleep Questionnaire (PSQ ≥ 8), Epworth Sleepiness Scale (ESS > 10), or Snoring Severity Scale (SSS ≥ 7) for children; Berlin Questionnaire (≥ 2 positive categories), ESS > 10, or SSS ≥ 7 for young adults. Tongue function included mobility, strength, posture, and orofacial domains. Multivariable logistic regression with backward stepwise selection was used in pooled and age-stratified models. Pre-specified interaction terms were systematically tested to explore effect modification between functional and anatomical factors.
resultsThe prevalance of high-risk classification was 26.8% in children, 11.9% in young adults, and 17.5% overall. In children, low tongue resting posture (AOR = 1.69) and frequent nocturnal open-mouth posture (AOR = 2.69) were independently associated with high-risk classification. In young adults, better orofacial function (AOR = 0.79), greater posterior mobility (AOR = 0.96), and higher posterior strength (AOR = 0.98) were protective. Posterior mobility and age group moderated the association between tonsillar hypertrophy and high-risk classification (AOR = 0.53 and AOR = 2.06, respectively), though not in age-stratified models. In children, combined tonsillar hypertrophy and restricted posterior mobility were associated with substantially higher prevalence (34.5% vs. 13.8%; dose-response p=.006).
conclusionsTongue function showed age-group-specific associations with questionnaire-based high-risk classification. Incorporating both anatomical and functional assessments within age-specific frameworks may improve early identification and inform future research.
