A unique case of bilateral sciatic nerve variation within the gluteal compartment and associated clinical ramifications.
Article in The Australasian medical journal, 2015. 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
An abnormal course of a nerve either through or around a muscle may yield multiple or anomalous muscle innervation. Further, if nerves are inappropriately trapped within the confines of a muscle or irregular boundaries, variant emergence of a nerve could give rise to symptoms of an entrapment neuropathy. Upon routine dissection in the Department of Anatomy at the American University of Antigua College of Medicine, bilateral variants in the emergence of the sciatic nerve from the pelvis to the gluteal compartment were discovered in an elderly adult female cadaver. In the left gluteal compartment, the sciatic nerve had a high division where the peroneal division exited the pelvis superior to the piriformis muscle while the tibial division exited inferior to the piriformis. In the right gluteal compartment, the peroneal division was observed to have exited the pelvis between a split piriformis muscle before it joined the tibial division of the sciatic nerve. Knowledge of such variations in the course of the sciatic nerve may improve diagnosis and treatment of pathologies in this region.
