Which skeletal pattern should consider the correlation between the tongue volume versus the upper airway and craniofacial structure? A cross-sectional descriptive study in Vietnamese.

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
contextNumerous studies worldwide have shown that there is a significant difference between tongue volume and pharyngeal airway volume in skeletal patterns Class I, Class II, and Class III. It is closely related to the position, size of the jaw bone and volume of the oral cavity. This distinction plays an important role in orthodontic evaluation and treatment planning, especially in patients at risk for airway obstruction during sleep.
objectiveTo evaluate the volume of the tongue and pharyngeal airway in adults with different malocclusion conditions, in order to clarify the relationship between tongue volume, pharyngeal airway volume and oral cavity volume. MATERIAL AND
methodsA cross-sectional descriptive prospective study analysis was conducted on 120 patients with varying skeletal patterns who sought examination and treatment at the Department of Dentistry and Maxillofacial Surgery, Can Tho University of Medicine and Pharmacy Hospital. Imaging data from these patients were used to evaluate the volume of the tongue and pharyngeal airway in adults with different malocclusion conditions.
resultsThe average volumes of TV (Tongue volume) and TPV (Total pharynx volume) in Class III malocclusion were the largest, with values of 57820.86 cm
conclusionsAn inverse correlation has been established between the TV/OCV (Tongue volume/Oral cavity volume) ratio and pharyngeal airway volume. This finding suggests that tongue volume, oral cavity volume, and their ratio influence airway patency. Understanding the relationship between the tongue and the airway in orthodontic treatment planning, particularly in improving airway space for patients with Class II malocclusion.
