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

Malocclusion may lead to the development of occlusal trauma, which can exacerbate periodontal disease. Here, we present a skeletal Class II adult patient with occlusal traumatic periodontitis of upper incisors, who was treated with a two-phased orthodontic treatment. In the first phase, a Twin Block appliance (TBA) was used to increase the vertical dimension of the posterior teeth, to eliminate the anterior occlusal trauma. In addition, TBA also improved mandibular retrusion by forwarding the mandible. In the second phase of fixed orthodontics, occlusion was fine-tuned with infrazygomatic crest (IZC) miniscrews and Class II intermaxillary elastics. At the end of treatment, anterior occlusal trauma was eliminated, periodontal conditions of upper incisors were improved, a stable occlusion and a harmonious profile were obtained. The successful two-phased orthodontic treatment showed that the TBA can effectively eliminate anterior occlusal trauma through restoration of posterior vertical dimension, and can improve mandibular retrusion by forwarding mandible and reconstructing stable occlusion in adult patient.
