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/Purpose: Orthognathic surgery can result in a decreased upper airway volume, potentially increasing the risk of developing sleep disorders. This study aimed to evaluate upper airway changes following bimaxillary orthognathic surgery and mandibular setback surgery alone. Additionally, to investigate any correlation between factors such as mandibular plane angle and mandibular length on airway changes in skeletal Class III patients, utilizing cone beam computed tomography (CBCT) data. Materials and methods: A total of 78 patients with maxillomandibular discrepancy ≤ -2 were divided to Group 1 (mandibular setback, n = 17) and Group 2 (maxillary advancement with mandibular setback, n = 61). CBCT scans were obtained 2-3 weeks preoperatively and 6 months postoperatively to measure airway volumes, minimal axial area, linear dimensions, and angles using Dolphin Imaging software. Statistical analyses, including the Wilcoxon signed-rank test and paired t-test, assessed pre- and postoperative effects, while Spearman's correlation evaluated the associations between variables and postoperative changes. Results: The results revealed a significant reduction in oropharynx volume (OPV), hypopharynx volume (HPV), total pharyngeal volume (TPV), and minimum cross-sectional area (CSA Conclusion: Both types of orthognathic surgeries caused significant decreases in total airway volume, CSA
