Endoscopic Treatment of Piriformis Syndrome Results in a Significant Improvement in Pain Visual Analog Scale Scores.
Article in Arthroscopy, sports medicine, and rehabilitation, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: To survey the clinical satisfaction of patients who have had an endoscopic piriformis release with a sciatic nerve neurolysis. Methods: Patients with piriformis syndrome (PS) who were treated with an endoscopic piriformis release combined with a sciatic neurolysis between 2013 and 2018 were identified. All patients had a minimum follow-up of 1 year. Patients were contacted by telephone in 201,9 whereby the rate of satisfaction and pain were evaluated with the Benson surgery scale and the visual analog scale (VAS). Results: The average duration of symptoms at first presentation was 34 months (range 16-54 months). Thirty-seven cases (82,2%) had an EMG that showed sciatic compression around the piriformis muscle. The average preoperative VAS pain score was 7.4 (± 0.8). The mean VAS score at the time of the survey was 1.9 (± 2.4). The difference in median preoperative and postoperative VAS was 6. Using the Wilcoxon signed-rank test, we found there was a significant improvement of VAS score (with Conclusions: Once a diagnosis is made, the endoscopic release of the piriformis tendon results in significant improvement in Pain VAS scores for patients with refractory symptoms despite conservative treatment. Level of Evidence: Level IV, therapeutic case series.
