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

Understanding changes in temporomandibular joint (TMJ) and ramus morphology in skeletal Class II and Class III jaw deformity patients before and after surgical orthodontic treatment is essential for achieving stable postoperative outcomes. Alterations in the positional relationship and morphology of the condyle, TMJ disc, and glenoid fossa can significantly influence postoperative occlusion and skeletal stability. Previous studies have demonstrated close associations among maxillofacial morphology, occlusion, and TMJ structure.In this narrative review, we summarize findings from our previous investigations regarding changes in TMJ morphology-including disc position, joint space, macroscopic morphology of the condyle and ramus, and computed tomography (CT) values-as well as considerations based on stress analysis in skeletal Class II and Class III deformities. These insights may contribute to a better understanding of anatomical characteristics of the TMJ in jaw deformity patients and may aid in predicting postoperative morphological changes.
