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: A horseshoe kidney is a rare congenital anomaly with complex vascular variations that increase surgical difficulty. Few reports have specifically addressed the vascular approaches in robot-assisted surgery. Case Presentation: A man in his 70s was diagnosed with right ureteral urothelial carcinoma in a horseshoe kidney. Preoperative imaging revealed a short renal artery arising posterior to the isthmus, suggesting difficulty with conventional surgical approaches. Surgery was initiated in the supine position using a medial approach, similar to the medial-to-lateral dissection used for sigmoid colon mobilization, with cranial dissection along the aorta to secure the vessel and isthmus, followed by repositioning and standard robot-assisted nephroureterectomy. Intraoperative indocyanine green fluorescence was used to guide safe isthmus division. The procedure was completed safely without any perioperative complications. Conclusion: A tailored approach based on detailed preoperative vascular assessment may facilitate safe and effective robot-assisted surgery in patients with horseshoe kidney and complex vascular anatomy.
