Biliary sludge and pigment stone formation in bile duct-ligated guinea pigs.
Article in Digestive diseases and sciences, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
We studied the effects of bile stasis in a guinea pig model of pigment gallstone. The common bile ducts of guinea pigs were partially ligated, and the guinea pigs killed one or two weeks later. Biliary sludge or stones were examined with the Fourier transform infrared spectroscopy and the scanning electromicroscopy. The bile was analyzed for pH, free calcium, bile acids and bilirubin fractions, and the activities of both bacterial and endogenous beta-glucuronidase. After bile duct ligation, calcium bilirubinate precipitates or stones formed in all except one of the animals studied. The bile pH and the proportion of unconjugated bilirubin rose after bile duct ligation, with a concomitant fall of bilirubin monoglucuronide. The activity of bacterial beta-glucuronidase decreased after ligation, while the activity of endogenous beta-glucuronidase rose at week 2. Our results imply that precipitation of calcium bilirubinate in this animal model was induced by an increased bile pH and the nonenzymatic hydrolysis of conjugated bilirubin.
