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

backgroundTemporomandibular joint ADD is highly prevalent and harmful, and some patients have no obvious clinical symptoms, but it can cause facial asymmetry, mandibular retrusion and other dental and maxillofacial deformities. Nevertheless, the impact of ADD on condylar height in individuals of varying age groups remains uncertain particularly with regard to condylar heights at different stages of development. The aim of this retrospective case-control study was to investigate the association between condylar height and temporomandibular joint anterior disc displacement (ADD) in different age groups. MATERIALS AND

methodsPatient characteristics, condylar height, disc length, and displacement distance at the baseline (T0) and the second follow-up visit (T1) were collected, and the differences between the two-time points were analyzed.

resultsA total of 149 patients who were diagnosed with unilateral ADD were included in the study. In comparison to T0, the affected condylar height decreased 0.66 mm, whereas the non-affected condylar height increased 1.37 mm at T1. The further subgroup analysis revealed no statistically significant change in the affected condylar height of the 11–17 age group. However, a considerable reduction in height was observed on the ADD side in the subgroup above 18 years, when compared to the T0 period.

conclusionsADD disrupts the normal development of condylar bone and cartilage in all age groups. Clinician recognises that ADD results in condylar height inhibition in the young and condylar height reduction in the adult.
