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

Bladder involvement in neurofibromatosis type 1 is rare. We report a pediatric case of bladder plexiform neurofibroma treated with partial cystectomy, ileal augmentation cystoplasty, and ureteral reimplantation. Although low-pressure urinary tract reconstruction was achieved, the patient did not regain the ability to void spontaneously, requiring long-term suprapubic cystostomy and ureteral stenting. Five years later, the patient developed retroperitoneal malignant peripheral nerve sheath tumor. Despite subtotal resection and pazopanib therapy, the disease progressed and the patient died at 14 years of age. This case highlights persistent functional morbidity and later malignant progression during the long-term course of NF1-associated pelvic disease.
