The relationship of pediatric obstructive sleep apnea with head and neck posture, hyoid bone position and airway dimensions.

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 cross-sectional study aimed to compare head and neck posture, hyoid bone position, and nasal and pharyngeal airway dimensions between orthodontic patients diagnosed with pediatric obstructive sleep apnea (OSA) and those with no risk of OSA. MATERIALS AND
methodsOSA group included 35 individuals (mean age = 12 ± 2.1 years; 16 female, 19 male) with an apnea-hypopnea index (AHI) greater than 1 confirmed via polysomnography (AHI = 6.3 ± 6.0). The control group included 35 age- and gender-matched individuals with no OSA risk as determined by a score of '0' on the Pediatric Sleep Questionnaire. Measured parameters included head and neck posture angles-cranio-cervical (SN-CVT°, SN-OPT°), cranio-vertical (SN-VER°, NL-VER°, ML-VER°), and cervico-vertical (OPT-VER°, CVT-VER°); hyoid bone position measurements-H-Mp, H-C3, H-Me distances; and airway dimensions-NAS, SPAS, MPAS, IPAS, PNS-U, and Sp1-Sp2. Intergroup comparisons were performed using independent samples t-test or Mann-Whitney U test, and Binary Logistic Regression analysis was performed.
resultsThere were no statistically significant differences between the groups regarding hyoid bone position or airway dimensions. However, the OSA group exhibited significantly greater cranio-cervical and cranio-vertical angles: SN-CVT (OSA: 111.3°±10.4°; Control: 106.6°±8.0°; P = 0.018), SN-VER (OSA: 103.7°±3.5°; Control: 100.7°±5.4°; P = 0.007), and NL-VER (OSA: 95.4°±3.8°; Control: 92.8°±5.0°; P = 0.018). ANB and NL-VER angles had significant effects on the groups.
conclusionPediatric patients with OSA, aged 9 to 16, demonstrated increased cranio-cervical and cranio-vertical angles, indicating a more extended head posture. This postural adaptation may serve as a clinical indicator of OSA in the pediatric orthodontic population.
