1 · What the graph read from it

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.

2 · The registry

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

objectiveThe present prospective clinical study aimed to investigate the effects of rapid maxillary expansion on the airway, correlating airway volumes obtained on multi-slice computed tomography and polysomnography assessment of oxygen saturation and apnea/hypopnea index.

methodsTwenty-four patients (11 with obstructive sleep apnea and 13 with residual snoring, mean age 10.0 (1.8), were enrolled in the study. Each patient underwent multislice computed tomography and nocturnal polysomnography before rapid maxillary expansion and after removal of maxillary expansion after six months. Airway regions were segmented, and volumes were computed.

resultsThe increase in oropharyngeal volume was significant in both groups. Oxygen saturation and apnea/hypopnea index were not statistically significant. No correlation was found between total airway volume, oxygen saturation, and apnea/hypopnea index changes between the time points examined.

conclusionsThis study showed that when rapid maxillary expansion is performed in individuals with sleep-disordered breathing, there were statistically significant differences in oropharyngeal volume between pre- and post-rapid maxillary expansion, but there was no correlation between oxygen saturation values and oropharyngeal volume increase. LEVEL OF EVIDENCE: The article is classified as Evidence Level 3 (Three).
