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

The Hem-o-Lok clip, a permanent polymer ligation device, is rarely associated with long-term complications like migration and tissue perforation. A 57-year-old male presented with right flank pain and ureteral obstruction. Imaging revealed a stone and severe hydronephrosis. Ureteroscopy identified an embedded Hem-o-Lok clip as the stone nidus. After failed endoscopic retrieval, robotic-assisted laparoscopic segmental ureterectomy with end-to-end anastomosis was successfully performed to remove the clip and reconstruct the ureter. This case highlights that migrated Hem-o-Lok clips can serve as a lithogenic nidus, causing ureteral obstruction. Standardized clipping technique and long-term follow-up are essential to mitigate such risks.
