Factors influencing the prediction of obstructive sleep apnea: an observational study from a developing country.

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
aimUpper airway anatomy is important in obstructive sleep apnea (OSA). This study conducted a correlation analysis between the apnea-hypopnea index (AHI) score and upper airway measurements obtained from cone-beam computed tomography (CBCT), arch measurements obtained from diagnostic casts, and subjective data from patients' records, including the Berlin Sleep Questionnaire and Epworth Sleepiness Scale.
methodsTwenty-five subjects with a confirmed diagnosis of OSA via polysomnography with a mean AHI of 25.5 (SD18.5) were enrolled in this study.
resultsA significant correlation was found between the AHI score and the following factors: male sex, obesity categories, Berlin questionnaire category, sleep efficiency, and maxillary intermolar width measured between the mesiobuccal cusp tip of the right and left first molars. Airway measurements from CBCT, including anterior cranial base length, facial proportion, and the length of the soft palate in the mid-sagittal plane and the retroglossal area in the axial plane, were significantly correlated with the AHI score.
conclusionIn addition to male gender and obesity, anatomic factors related to upper airway measurements on CBCT are significantly correlated with AHI, indicating upper airway limitations, OSA severity, and aiding early diagnosis.
