Effectiveness of Ultrasound-Guided Hydrodissection for Atypical Anterior Cutaneous Nerve Entrapment Syndrome Presenting as Lower Back Pain Due to Retrograde Neuropathic Pain.

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
This case report describes an atypical presentation of anterior cutaneous nerve entrapment syndrome (ACNES). A male patient with refractory lower back pain without typical abdominal symptoms exhibited localized tenderness in the abdominal wall. The patient's back pain was reproduced by compression of the tender point. Color Doppler ultrasonography revealed a pulsating perforating artery directly beneath the tender point. Ultrasound-guided hydrodissection was performed at the site, resulting in resolution of Carnett's sign and significant improvement in both pain and motor function. This case suggests that retrograde neuropathic pain (RNP) may arise from entrapment of the anterior cutaneous nerve, manifesting as referred pain in the lower back. Even in the absence of abdominal symptoms, a positive Carnett's sign should prompt the consideration of abdominal wall nerve entrapment and associated RNP in the differential diagnosis of refractory low back pain.
