1 · What the graph read from it

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.

2 · The registry

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

We report a rare case of obturator nerve schwannoma incidentally found during laparoscopic radical prostatectomy in a 68-year-old man with a 20-year history of chronic thigh pain. Initially interpreted as lymphadenopathy on MRI, the lesion was excised via intracapsular, nerve-sparing resection. Histopathology confirmed a benign schwannoma. The patient experienced >90 % pain relief, regained urinary continence by day 30, and is recovering erectile function. At six months, he remains symptom-free. Obturator schwannomas are extremely rare and can mimic nodal disease. Minimally invasive, nerve-sparing excision during pelvic oncologic surgery is safe and effective when performed by experienced surgeons.
