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

PCR was performed for the detection of Helicobacter pylori in feces from 24 patients with proven infections. Several precautions were taken to overcome possible inhibition of PCR with feces. In the first 12 patients, feces were examined shortly after endoscopy. In another group of 12 patients, who were treated during 2 weeks with omeprazole (40 mg each day) to increase gastric pH, feces were examined as well. H. pylori target DNA could not be detected in the stools of any of the 24 infected patients. It was concluded that there was no substantial shedding of H. pylori in feces from either group of patients.
