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

Double duct sign where there is a simultaneous dilatation of both the common bile duct (CBD) and pancreatic duct is usually associated with sinister causes like malignancies of pancreatic head or ampulla. Occasionally, benign causes like chronic pancreatitis or sphincter of Oddi dysfunction (SOD) may cause double duct sign. Chronic opium abuse is a rare cause of the double duct sign, and endoscopic ultrasound (EUS) findings of this rare entity have been occasionally reported. We report about a 54-year-old male with a history of chronic alcohol and opioid abuse evaluated for episodes of abdominal pain and found to have opioid-related SOD and improved with biliary sphincterotomy. EUS was done to rule out malignancy and revealed hypoechoic prominence around terminal CBD suggestive of hypertrophied muscle.
