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

introductionThis study investigated changes in the morphology of the mandibular symphysis and the movement of the mandibular incisor over time during surgical orthodontic treatment for skeletal class Ⅲ.

methodsTwenty-two patients with skeletal class Ⅲ malocclusion treated with combined orthodontic treatment, and orthognathic surgery were included. Multidetector computed tomography (CT) and lateral cephalograms were obtained from these patients to assess changes in mandibular incisor inclination, position, labial and lingual bone area, alveolar bone thickness at the mandibular central incisors and canines, and the morphological evaluation of the mandibular symphysis.

resultsThe lower alveolar bone thickness at the incisors showed a significant increase, whereas the lingual alveolar bone area significantly decreased. Additionally, the incisor mandibular plane angle (IMPA) significantly increased. Labial tipping of the mandibular incisors during presurgical orthodontic treatment resulted in the root apices moving closer to the lingual cortical bone. During postsurgical orthodontic treatment, the position of the incisor root apices remained stable, while the incisor crowns underwent lingual movement.

conclusionMandibular incisors incline labially during presurgical orthodontics accompanied by the lingual inclination of the mandibular symphysis. These findings highlight the dynamic changes in alveolar bone and root position during orthognathic surgical treatment.
