A minimally invasive surgical approach for the treatment of piriformis syndrome: a case series.
Article in Chinese neurosurgical journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05404607 (Comparative Effects of Fascial Distortion Model With and Without Neuromuscular Inhibition Technique on Pain, Range of Motion and Quality of Life in Patients With Piriformis Syndrome), which is not on this map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
backgroundPiriformis syndrome accounts for approximately 6% of patients who present with sciatic pain. There are many treatment options ranging from physical therapy, to trigger point injections, to surgical intervention. We discuss a surgical method that represents a minimally invasive technique for the treatment of piriformis syndrome.
methodsWe describe a novel operative approach and technique for release of the piriformis muscle in the treatment of piriformis syndrome. Described are the preoperative planning, incision and approach, and technique for identifying and releasing the piriformis muscle.
resultsThree patients were treated for piriformis syndrome using the described technique. Each patient displayed successful relief of their symptoms immediately following the surgical procedure and at delayed follow-up.
conclusionEarly experience with our method of piriformis release suggests that it is well suited for the treatment of piriformis syndrome. The novel integration of pre-operative trigger point localization coupled with intraoperative neuromonitoring allows effective pain relief with minimal morbidity.
