Factors affecting postoperative nasal morphology after Le Fort I osteotomy on multiple regression analysis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Changes in external nasal morphology after Le Fort I osteotomy can lead to reduced patient satisfaction and diminished quality of life postoperatively. Despite various modifications such as alar cinch suture and subspinal osteotomy to overcome such changes, the external nasal morphology may vary unexpectedly on an individual basis. This report investigated the factors influencing the changes in external nasal morphology, by considering the patient's preoperative external nasal morphology as well as the surgical technique, and the direction of repositioning of maxilla. Multiple regression analysis identified the patient's preoperative nasal width as a factor that increased the alar base width of the nose, in addition to incision (oral vestibular incision) and the amount of anterior and superior movements at point A of the maxilla. The factors that caused the nasal tip to turn upward were the amount of anterior and superior movements at point A and the absence of subspinal osteotomy. The direction of surgical maxillary movement was influenced not only by anterior movement, but also by superior movement and surgical technique. The patient's preoperative nasal morphology should also be considered during the preoperative planning for orthognathic surgery to ensure optimal esthetic and functional outcomes.
