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
Purpose: The ERS Statement dealing with childhood obstructive sleep apnea (OSA) declared that cephalometry and acoustic pharyngometry may be useful exams for the management of OSA. The objective of our cross-sectional study was to evaluate the correlations between the severity of OSA, namely obstructive apnea-hypopnea index (OAHI), and indices obtained from both acoustic pharyngometry and cephalometry in children referred for OSA treatment. Methods: Children referred for treatment of their moderate to severe OSA (AHI ≥ 5/hour) underwent acoustic pharyngometry in sitting and supine positions (measurement of pharyngeal volume and calculation of estimated pharyngeal compliance) and cephalometry (measurement of Frankfort Mandibular plane Angle: FMA and Frankfort Mandibular Incisal Angle: FMIA, hyoid bone distance to mandibular plane). Results: Two hundred and five consecutive children were enrolled (mean age ± SD: 11.2 ± 3.7 years, 73 females, type 1 OSA "enlarged tonsils": 55 children, type 2 "obese": 80, type 3 "syndromes": 70). In a multiple regression analysis, only FMA and hyoid bone distance remained independently linked to OAHI (adjusted r Conclusion: Childhood OSA can be associated with hypodivergence. Its severity is linked to craniofacial morphology, and cephalometry provides additional endotypic information in selected children.
