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
Background: The aim of this study was to compare oropharyngeal airway measurements among high- and low-risk individuals for obstructive sleep apnea syndrome. Materials and Methods: In this cross-sectional study on patients referred for cone-beam computed tomography (CBCT) imaging before dental implant surgery, inclusion criteria were individuals aged >30 years, Class I occlusion, without anomalies of the head and neck, dentulous individuals, systemically healthy, and without defects in the airways. The exclusion criteria were individuals whose responses to the study questionnaires did not match that of their companions and images with artifacts. These patients and their relatives/housemates were requested to fill in the Epworth Sleepiness Scale and Berlin questionnaires. Based on the answers, the patients were classified as high-risk groups, and patients formed low-risk groups. CBCT images were obtained with 85 kVp and 35 mAs and analyzed using ITK-Snap and Mimics. Oropharyngeal airway volume, minimum cross-sectional area, both mesiodistal and anterior-posterior distances in the same axial cut, and linear length between the posterior pharyngeal wall and nasal spine/soft palate/tongue on the midsagittal slice were measured. The level of significance was considered 0.05 for the independent samples Results: In total, 32 individuals participated with a mean age of 50.2 and 53.2 years in the high-risk and low-risk groups, respectively. Ten females and six males comprised the high-risk group, and eight females and eight males formed the low-risk group. Higher BMI and neck circumference existed in the high-risk group, and they both showed a direct relationship with the Epworth score. Oropharyngeal measurements presented significant differences between the two groups, except for the distance between the base of the tongue and the posterior pharyngeal wall ( Conclusion: Oropharyngeal airway volume and minimal cross-sectional area can be used as a predictor for obstructive sleep apnea, and CBCT imaging is beneficial for this purpose.
