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
Spasticity affects up to 80% of stroke survivors and is associated with significant pain, impaired function, and reduced quality of life. In patients with end-stage renal disease, severe upper limb spasticity presents additional challenges by restricting positioning for arteriovenous fistula (AVF) creation. Oral antispasmodic agents are often poorly tolerated because of impaired renal clearance and systemic side effects. Although alcohol neurolysis is an established intervention for focal spasticity, its use to facilitate AVF creation has not been previously described. We report the case of a 53-year-old woman with newly diagnosed end-stage renal disease who developed multi-territorial strokes resulting in severe generalized spasticity (Modified Ashworth Scale 3-4) with associated pain and abnormal limb posturing. Spasticity presented a major barrier to AVF creation. Oral agents, including baclofen and tizanidine, were avoided or discontinued because of safety concerns in the setting of ESRD with recurrent intradialytic hypotension. Botulinum toxin injections improved pain but failed to restore sufficient range of motion. At 7 months after her strokes, she underwent ultrasound-guided alcohol neurolysis of the right musculocutaneous and median nerves. This produced significant spasticity reduction (elbow flexors: Modified Ashworth Scale 3→1+; forearm pronators: 3→1; wrist flexors: 4→2 by 28d), pain resolution, and improved joint mobility, enabling successful right radiocephalic AVF creation under local anesthesia 13 days later without complications. To our knowledge, this is the first reported case of alcohol neurolysis facilitating AVF creation in a dialysis-dependent stroke patient with refractory spasticity. This case highlights alcohol neurolysis as a safe and effective intervention when systemic agents and botulinum toxin are unsuitable or inadequate, and underscores the importance of an individualized, multimodal, and multidisciplinary approach to spasticity management in complex patients.
