Piriformis Syndrome (Sciatic Nerve Entrapment) Associated With Type C Sciatic Nerve Variation: A Report of Two Cases and Literature Review.
Article in Korean journal of neurotrauma, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Although anatomical variation of the sciatic nerve and piriformis muscle at the greater sciatic notch is considered an important cause of piriformis syndrome, there are few reports on the surgical treatment of piriformis syndrome owing to specific anatomical variations of the sciatic nerve and piriformis muscle. In this report, we describe 2 cases of piriformis syndrome caused by a rare type C sciatic nerve variation that were surgically treated using the transgluteal approach. The first patient reported unremitting left hip and leg pain that occurred following blunt trauma to the hip. The second patient complained of chronic pain in the buttocks and right leg, which persisted even after the patient underwent lumbar fusion surgery. Severe sitting pain and sciatica are symptomatic indications for the diagnosis of piriformis syndrome. A rare "C" type sciatic nerve variation was observed on the affected side under magnetic resonance imaging. Transgluteal sciatic nerve decompression provided significant pain relief. If severe sciatic nerve deformation due to a rare sciatic nerve variation can be confirmed with typical findings of piriformis syndrome, the possibility that sciatic nerve entrapment may have occurred in this variation should be considered.
