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

objectiveThis study aimed to determine if tonsillar hypertrophy (TH) influenced the postsurgical skeletal stability of Class III patients receiving two-jaw orthognathic surgery. MATERIALS AND

methodsSixty patients with skeletal Class III malocclusion corrected by conventional two-jaw surgery were included in the study. Patients were divided into the TH group (n = 30) and normal tonsil (NT) group (n = 30) depending on tonsil size on the presurgical cone beam computed tomography. Serial lateral cephalograms were traced and analyzed at 3 stages: before surgery (T0), within 2 weeks of surgery (T1), and 1 year after surgery (T2). Linear and angular cephalometric parameters were used to evaluate the surgical change (T0-T1) and postsurgical relapse (T1-T2). The data were analyzed with the paired t-test, independent t-test, chi-square test, correlation analysis and regression analysis.

resultsFrom T0 to T1, the TH and NT groups showed a similar surgical pattern of the maxilla and mandible for repositioning. From T1 to T2, significant differences in skeletal relapse were observed in the mandible horizontally but not in the maxilla between the 2 groups. Compared to the NT group, the TH group exhibited significantly more forward movement at point B as well as a greater increase in SNB angle one year after surgery.

conclusionsSkeletal Class III patients with TH presented less skeletal stability of the mandible following two-jaw orthognathic surgery compared to those with NT. The factor of TH needs to be considered when orthognathic surgery is indicated in Class III patients.
