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

introductionThe present study aimed to preliminarily compare the differences of the condyle relocation range (CRR) between skeletal class II and skeletal class III patients.

methodsTwenty skeletal class II and twenty skeletal class III young adult patients underwent wide-field cone beam computed tomography (CBCT) scans of the maximum intercuspation position (MIP) and most comfortable forward relocation (MCFR). We superimposed the CBCT images in two positions according to the bilateral zygomatic bone surface structure and then measured the dental and skeletal CRRs in three-dimensional space.

resultsThe median (interquartile range) dental and skeletal CRRs of skeletal class II malocclusion patients were 8.71 (3.55) mm and 8.47 (4.19) mm, respectively. The median (interquartile range) dental and skeletal CRRs for skeletal class III malocclusion patients were 1.37 (3.43) mm and 1.04 (1.44) mm, respectively. Both the dental and skeletal CRRs of skeletal class II patients were significantly greater than those of skeletal class III patients (p < 0.01).

conclusionsThe CRRs of the different skeletal types exhibit obvious differences. Therefore, the range of physiological mandible positions in patients should be given attention during orthodontic diagnosis and treatment.
