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
introductionThis retrospective report summarizes observations from eight operations where the endoscopically assisted approach was used to explore Guyon's canal syndromes of idiopathic aetiology.
aimTo evaluate the feasibility and limitations of endoscopic Guyon's canal release performed from a distal forearm incision. MATERIAL AND
methodsEight charts and video records of eight ulnar tunnel syndrome patients presenting concomitant idiopathic Guyon's canal syndromes were retrospectively reviewed. In all cases endoscopically assisted explorations in Guyon's canals with simultaneous cubital tunnel releases were performed.
resultsIn all of the patients the multiple tight bands of the superficial volar carpal ligament forming the canal roof were divided. Some of these bands crossing the nerve in its direct vicinity could have been responsible for the constriction. We were also able to divide the proximal segment of the canal floor. We have observed, however, that the proximal to distal endoscopic dissection jeopardizes the motor branch of the ulnar nerve; therefore, it should not be used to release the pisohamate ligament, or the hypothenar fascia.
conclusionsAlthough all of the patients showed improvement, we cannot recommend this method in its current form. We are of the opinion that safe endoscopic Guyon's canal operations may require a different approach.
