Lemmel Syndrome Without Choledocholithiasis as a Cause of Recurrent Hepatocellular Injury: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Lemmel syndrome is a rare cause of stone-negative biliary obstruction due to external compression of the distal common bile duct by a periampullary duodenal diverticulum (PAD). We report a 67-year-old man with recurrent episodes of liver dysfunction due to Lemmel syndrome. On admission, laboratory tests showed marked hepatocellular injury with cholestasis. Contrast-enhanced CT demonstrated a PAD abutting and compressing the distal bile duct with upstream dilatation, without choledocholithiasis. Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and balloon sweeping yielded sludge-like bile, after which liver tests rapidly improved. This case underscores the need to consider PAD-related transient obstruction in stone-negative, recurrent hepatocellular flares and highlights the diagnostic-therapeutic value of timely endoscopic biliary decompression.
