Experimental study on mandibular length and facial symmetry of low estrogen level and anterior disc displacement of temporomandibular joint.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
This study was aimed at elucidating the changes of mandible symmetry in a rabbit model with low estrogen levels induced by ovariectomy (OVX) combined with temporomandibular joint (TMJ) anterior disc displacement without reduction (ADDWoR). 32 growing rabbits were randomly allocated into 4 groups; OVX group, ADDWoR group, OVX+ ADDWoR group and control group. In OVX and OVX+ ADDWoR groups, bilateral OVX was performed and then the serum level of 17β-estradiol was evaluated every week. In ADDWoR group and OVX+ ADDWoR group, the right TMJ was surgically opened and the disc was displaced anteriorly and the left TMJ was also surgically opened and closed without any manipulation of the disc. All rabbits had CT scan before and at the end of the study and the mandible measurements were performed on the 3D-reconstructed model. The mandible in ADDWoR group was consistently shorter on the right side resulting in a midline shift to the ipsilateral side. While in OVX+ ADDWoR group, the mandibular length of the right side was more shorter than in ADDWoR group, moreover, mandibular deviation was therefore more severe. In OVX group, there was no difference regarding the length of mandible compared to the control group. There was no difference regarding the mandibular length between left and right sides in the control group.
