1 · What the graph read from it

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.

2 · The registry

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

objectivesThis study aims to assess the stability of soft tissues one and three years after orthognathic mandibular advancement surgery by superimposing the cone-beam computed tomography (CBCT) images and quantifying potential soft tissue changes following surgery. MATERIALS AND

methodsIn this prospective observational study, changes in the hard and soft tissues of the chin, lower incisors, and lower lip due to displacement and/or bone remodeling were analyzed using three-dimensional models based on CBCT superimposition images acquired before surgery (T0), one year after surgery (T1), and three years after surgery (T3). The cranial base was used as a reference for the superimpositions, which were based on fully automated grayscale voxel-wise registrations.

resultsThe soft chin showed more than 2 mm displacement between T0 and T1 and between T0 and T3, along with hard chin displacement. The lower lip had less displacement at T0 and T1. The soft tissue adaptation between T1 and T3 indicates stability of the soft tissue correction.

conclusionEven though the soft tissue three-dimensional response one year after surgery was variable, the investigated anatomical regions were stable between one- and three years post-surgery, and only the soft chin exhibited some relapse. The soft tissue chin changes observed were strongly correlated with the hard chin. CLINICAL RELEVANCE: This study provides comprehensive and long-term insights considering soft tissue facial features' stability after orthognathic surgery, impacting orthodontic treatment planning, and integrating both problem-oriented and goal-oriented approaches. The outcomes emphasize the importance of surgical aesthetics alongside occlusion, ultimately contributing to better long-term results and enhanced patient satisfaction.
