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.

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
Pronator teres syndrome (PTS) is an uncommon neuropathy caused by compression of the median nerve at the proximal forearm, resulting in paresthesia and pain in the radial digits. Although conservative management is typically the preferred initial approach, chronic and refractory cases often require multimodal treatment strategies. A 55-year-old female truck driver presented with a five-year history of persistent bilateral numbness and pain radiating from the palms to the distal phalanges. Physical examination revealed positive pronator compression and bilateral upper limb neurodynamic tests, with a numerical rating scale (NRS) score of 8/10. Palpation during ultrasound imaging demonstrated localized tenderness and radiating pain around the pronator teres and median nerve. Cervical pathology and carpal tunnel syndrome were excluded. The patient underwent ultrasound-guided hydrodissection of the median nerve at the pronator teres level every two weeks, combined with manual mobilization and a prescribed home-based exercise program. Symptomatic relief was achieved after the first session, and after four treatment sessions over two months, the NRS score improved from 8/10 to 3/10. Functional recovery was achieved, and the patient successfully maintained symptom control through continued adherence to the home-based exercise program. This report highlights the potential effectiveness of a multimodal strategy for addressing chronic PTS. Ultrasound-guided hydrodissection may improve mobility of the median nerve by reducing perineural restrictions, while manual mobilization and gliding exercises are likely to provide complementary therapeutic effects. Given the chronicity of the patient's condition, the early and sustained response underscores the potential utility of combining these techniques in refractory cases. Ultrasound-guided hydrodissection, when combined with manual therapy and a structured home-based exercise program, may represent a minimally invasive and effective management option for chronic pronator teres syndrome that is unresponsive to conservative care.
