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
introductionMultiple sampling from different sites of the stomach as well as the number of fragments of gastric mucosa available for histopathologic evaluation are important sources of variation when classifying and grading chronic gastritis.
objectiveTo estimate the sensitivity of the number of fragments of gastric mucosa necessary to establish the diagnosis of atrophic gastritis with intestinal metaplasia, gastric dysplasia and
methodsThis is a 6 year-cohort study, wherein 1958 gastric endoscopic procedures performed by two gastroenterologists were reviewed. Five gastric biopsy samples were obtained from the antrum, body and lesser curvature during each procedure. One pathologist was in charge of reviewing the five histopathology samples for each subject and providing a definitive diagnosis which was used as the gold standard. Each gastric mucosa sample reviewed led to an individual diagnosis for that sample which was compared with the gold standard. Intra-observer variability was assessed in 127 individuals who correspond to a random sample of 20% of the total endoscopic procedures performed during the 72 month-follow-up.
resultsThe sensitivity of the diagnosis of intestinal metaplasia (IM) and gastric dysplasia increased proportionally with the number of gastric mucosa samples reviewed. The lesser curvature of the stomach had the highest sensitivity for the diagnosis of IM and dysplasia, among all the stomach regions studied. Just one sample of gastric mucosa attained a sensitivity of 95.9% for the detection of
conclusionThe number of mucosa gastric fragments reviewed, the fixation method used, and the biopsy site are all important factors in order to ensure a correct classification of chronic gastritis.
