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 is an effective treatment for skeletal Class III malocclusion; however, the relative influence of skeletal and soft tissue variables on postoperative esthetic outcomes remains unclear. This study aimed to evaluate the relationships among cephalometric parameters, soft tissue changes, and esthetic outcomes following single-jaw mandibular setback surgery. Materials and methods: A retrospective study was performed on 258 adult patients with skeletal Class III malocclusion subspinale-nasion-supramentale (ANB) angle <0° who were treated between 2016 and 2021. Patients were divided into three groups: bilateral vertical ramus osteotomy (BVRO) group (n = 99), genioplasty alone group (n = 30), and BVRO plus genioplasty group. (n = 129). Cephalometric and soft tissue variables, including nasolabial angle, lip position relative to the Ricket esthetic line (E line), vertical height, and occlusal plane angle, were evaluated. Statistical analyses included multiple regression and receiver operating characteristic curve (ROC) analysis. Results: Postoperative esthetic outcomes based on the E line were achieved in approximately 47-50% of patients across groups. Significant improvements in sella turcica-nasion-subspinale (SNA) angle, sella turcica -nasion-supramentale (SNB), sella turcica -nasion-symphysis center (SND), and Wits appraisal were observed ( Conclusion: Both skeletal and soft tissue variables influence esthetic outcomes. A multifactorial evaluation is essential for optimizing surgical planning in skeletal Class III patients.
