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

objectivesThe present study was aimed to assess three-dimensional (3D) quantitative changes of condyle in patients with Class III facial asymmetry after bimaxillary orthognathic surgery. MATERIALS AND

methodsFifty-five eligible patients with Class III facial asymmetry received Le Fort I osteotomy and bilateral sagittal split osteotomy (BSSO) with or without genioplasty from January 2020 to June 2022 were included. Cone-beam computed tomography (CBCT) for each patient was collected at 3 stages: 1 week preoperatively (T0), immediately after surgery (T1) and at least 12 months postoperatively (T2). Positional changes and bone remodeling of condyles were measured based on voxel- and surface-registrations using ITK-SNAP and 3D Slicer and compared between various stages. Correlations between these changes, mandibular surgical movements and skeletal stability were further explored.

resultsMost condyles at deviated side (DS) tended to shift inferiorly, anteriorly and to non-deviated side (NDS), while condyles at NDS were displaced posteriorly, inferiorly and laterally from T0 to T1. Condyles showed upward pitch, outward yaw and lateral roll at both sides. Bone resorption was more frequently observed in the posterior area of condylar surface at NDS. Significant correlations were found between mandibular anteroposterior/transverse stability and DS condylar lateral shift or NDS condylar yawing after surgery (T1-T2), respectively.

conclusionsOur results comprehensively characterize 3D condylar changes and their associations with skeletal stability after surgical correction of Class III facial asymmetry. CLINICAL RELEVANCE: These findings advance current understanding of complex condylar changes after bimaxillary orthognathic surgery in Class III facial asymmetry patients.
