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

Introduction: Persistent perineal wetness in adults with normal standard imaging is uncommon and may indicate rare congenital anomalies such as urethral duplication. Case Presentation: A man in his early 20s presented with a 3-year history of intermittent perineal wetness of unknown origin. Extensive gastrointestinal and urological investigations were unrevealing. Indigo carmine administration confirmed urinary leakage, prompting focused evaluation. Endoscopic assessment with meticulous perineal inspection under general anesthesia identified a tiny, non-inflamed perineal opening. Fistulography and cystoscopy demonstrated an accessory tract arising from the prostatic urethra and opening to the perineum, consistent with Effmann type IIA2 Y-type urethral duplication, extremely rare in adult-onset. Complete excision was achieved using a combined perineal and laparoscopic transabdominal approach with light-emitting catheter guidance, preserving urinary continence and erectile function. Symptoms resolved immediately without recurrence. Conclusion: This case highlighted key diagnostic pitfalls and demonstrates effective surgical management of adult-onset type IIA2 Y-type urethral duplication.
