Adenoid hypertrophy is directly associated with the severity of OSA in obese children: A pilot study.
Article in Brazilian journal of otorhinolaryngology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveThis study aimed to evaluate which physical findings, observed during both awake and DISE examinations, correlate best with polysomnographic severity in obese children with Obstructive Sleep Apnea (OSA).
methodsChildren diagnosed with pediatric OSA and obesity (BMI > 95th percentile) were evaluated. All underwent polysomnography to confirm the OSA diagnosis. Demographic data, physical exams, and ENT clinical evaluations were also collected. DISE (drug induced sleep endoscopy) was performed just before adenotonsillectomy, following Boudewyns' protocol to assess pharyngeal collapse.
resultsNineteen obese children with OSA were evaluated, with 37% showing adenoid hypertrophy (>75%) on nasal endoscopy, and 53% presented tonsillar hypertrophy on physical examination. The median AHI (apnea / hypopnea index) was 7 (range: 3; 17): 9 had mild, 2 moderate, and 8 severe OSA. Children with adenoid hypertrophy had higher arousal indices, AHI, REM (rapid eye movement) AHI, OAHI (obstructive AHI) and lower minimum saturation compared to those without obstruction, in both awake and DISE evaluations. The presence of other factors, such as tonsillar hypertrophy, tongue base obstruction, palatal and epiglottic collapses, or hypotonia, was not associated with OSA severity or polysomnographic findings in either awake or DISE exams.
conclusionIn our cohort, adenoid hypertrophy was the factor most strongly correlated with OSA severity in obese children. This correlation was consistent between awake physical examination and DISE findings. LEVEL OF EVIDENCE: 3:
