Rapid maxillary expansion and its impact on sleep apnea in children aged 5 to 8 years: a retrospective 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
objectiveDetermine the impact of early transverse maxillary expansion on the symptomatic manifestation of sleep apnea in children aged 5-8 years.
methodsNineteen patients (mean age: 6.84 years) with maxillary constriction underwent rapid maxillary expansion (RME) for orthodontic treatment. Inclusion criteria: age 5-8 years, Apnea-Hypopnea Index (AHI) > 1, treated with Memory screw Hyrax appliance, under pediatric sleep physician care. Exclusion criteria: non-compliance, re-evaluation delays (> 3 months). Primary variable: AHI before (T0) and after (T1) expansion. Treatment ended based on malocclusion correction. AHI comparisons included dentition status and gender as secondary variables.
resultsA paired t-test showed no significant difference in the mean AHI between T0 (4.05±2.55) and T1 (3.68±3.12) for primary variables (p>0.05). At T0, no significant AHI difference was found between genders (F: 3.21±2.47; M: 4.09±2.87, p>0.05). After expansion (T1), a significant change was observed between genders (F: 1.75±1.03; M: 5.18±3.68, p<0.05). There was also no significant difference in AHI changes based on dentition status. A negative correlation was found between AHI changes and transverse changes and at canine and molar levels.
conclusionNo significant evidence was found to support the effectiveness of early maxillary expansion in improving sleep apnea among children with maxillary constriction. However, the gender-specific responses and the potential dose-response relationship between maxillary expansion and AHI reduction highlight the complexity of treating pediatric OSA.
