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
backgroundIntrapelvic entrapment of the sciatic and sacral nerve roots can cause chronic pelvic pain, sciatica, and symptoms such as dysmenorrhea, dyspareunia, dyschezia, dysuria, vulvodynia, coccygodynia, and pudendal neuralgia. Conventional spine-focused approaches often overlook this cause. This study assessed whether laparoscopic nerve decompression improves pain and related outcomes.
methodsBetween November 2022 and April 2024, 25 women (median age: 36 years) with ≥ 2 years of refractory pelvic neuropathic pain underwent laparoscopic decompression of the sciatic and sacral plexus. Diagnosis was confirmed via neuropelveological exam and 3-Tesla MRI. Patient-reported outcomes-Visual Analogue Scale (VAS) for nine pain domains, SF-36, PHQ-9, and OAB-V8-were collected preoperatively and at 1, 6, and 12 months postoperatively. Operative details and complications were recorded.
resultsAll surgeries were completed laparoscopically with no conversions or motor deficits. Median operative time was 143.5 min. VAS scores decreased by 70-90% at one month (p ≤ 0.001) and remained improved at 6 and 12 months. SF-36 subscales improved significantly by month 1 and peaked at month 6. PHQ-9 dropped from 18.2 to 6.8 at 12 months (p < 0.001). OAB-V8 scores also showed significant improvement (p < 0.05).
conclusionsLaparoscopic decompression of intrapelvic sciatic and sacral nerves appears safe and effective, providing substantial and sustained improvements in pain, quality of life, mood, and bladder symptoms. Further randomized trials are needed to validate these findings.
