The prevalence of helicobacter pylori among dyspeptic patients in an earthquake-stricken area.
Article in Clinics (Sao Paulo, Brazil), 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesHelicobacter pylori is a gram-negative, spiral-shaped, urease-producing bacterium with multiple unipolar flagella. Humans are a major reservoir for H. pylori; however, there are no data on the prevalence of H. pylori among dyspeptic patients who have experienced natural disasters. Therefore, the aim of this study was to examine the prevalence of H. pylori in dyspeptic patients who survived a recent natural disaster and to compare the data between the pre-disaster and post-disaster periods.
methodsBetween December 2011 and February 2012 (∼ one month following an earthquake), 209 dyspeptic patients who underwent gastroscopy were included in the study. For microorganism identification, gastric biopsy materials from the 209 disaster survivors with dyspeptic complaints were tested for urease activity in a medium containing urea and a pH indicator. The obtained results were compared with pre-disaster data from dyspeptic patients in the same city during the corresponding period of the previous year. Furthermore, the current H. pylori prevalence was evaluated among 139 dyspeptic patients between January 2014 and May 2014.
resultsWe found a significantly higher prevalence of H. pylori in disaster survivors with dyspepsia compared with dyspeptic patients in the pre-disaster period (p<0.005). Interestingly, the current H. pylori prevalence was found to be significantly higher than the prevalence in both the disaster and pre-disaster periods (p<0.005).
conclusionThese results suggest that a recent earthquake could contribute to the development of H. pylori infection in subjects who live in the disaster-stricken area. These data also highlight the exceptionally high H. pylori prevalence in dyspeptic patients. Regional variations require further analyses.
