MUC 1 mucin content in gastric juice of duodenal ulcer patients: effect of Helicobacter pylori eradication therapy.
Trial report in Clinical and experimental medicine, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
It has been suggested that Helicobacter pylori can interact via carbohydrate structures with gastric mucins. Particularly, the Lewis b structures of the secretory MUC 5AC mucin are considered to be putative receptors for bacterial adhesins. Also the epithelial MUC 1 mucin is implicated by some authors to have a major role in the mechanism of infection. The main objective of our study was to evaluate MUC 1 mucin levels in human gastric juice before and at the end of eradication therapy. Any possible changes could suggest the participation of MUC 1 in H. pylori infection. We assume that the amount of the soluble form of MUC 1 exfoliated to the juice correlates with MUC 1 expressed on epithelial cells. Gastric juice samples of 14 duodenal ulcer patients infected with H. pylori were assayed before and at the end of eradication. In all samples, DNA content was determined. Mucin fractions were isolated by gel exclusion chromatography. High molecular mass material containing MUC 1 was subjected to 4%-12% polyacrylamide gradient gels, electrotransfer to Immobilon P and immunodetection. In 12 infected patients (86%), the initial low level of MUC 1 mucin in gastric juice increased at the end of eradication. In comparison to the infected patients, neutral carbohydrate and DNA content in gastric juice diminished after treatment. Our results indicate that the bacterium affects the soluble form of MUC 1 mucin, thus suggesting a likely role of this mucin in the course of H. pylori infection.
