Intermittent Hematuria and Shock due to Uretero-Arterial Fistula Diagnosed by Provocative Angiography.

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
Uretero-arterial fistula is a rare but life-threatening cause of massive hematuria. A 78-year-old woman with a history of pelvic surgery, radiation therapy, ileal conduit diversion, and long-term ureteral stenting presented with gross hematuria and anemia. Contrast-enhanced computed tomography (CT) and repeated angiography failed to identify the bleeding source. During recurrent hemorrhage, provocative angiography with negative-pressure aspiration through a ureteral catheter demonstrated extravasation from the right common iliac artery. Endovascular stent-graft repair achieved immediate hemostasis. This case highlights the diagnostic value of provocative angiography in challenging cases of uretero-arterial fistula.
