The Effect of Helicobacter pylori Infection, Aging, and Consumption of Proton Pump Inhibitor on Fungal Colonization in the Stomach of Dyspeptic Patients.
Article in Frontiers in microbiology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundThe importance of coinfection of Helicobacter pylori (H.pylori) and Candida albicans (C. albicans) in the development of gastric diseases is not known. In this study, the frequency of concurrent infection of H. pylori and C. albicans in dyspeptic patients was assessed while considering age, gender, and PPI consumption of patients.
methodsGastric biopsies were taken from 74 yeast-positive dyspeptic patients and gastric disease, age, gender, and proton pump inhibitor (PPI) consumption of subjects were recorded. One antral biopsy was used for rapid urease test (RUT) and one for H. pylori and yeast cultivation and smear preparation. Bacterial isolates were identified according to spiral morphology and the biochemical characteristics. Yeast isolates were identified on Chromagar and by the Nested-PCR amplification of C. albicans-specific topoisomerase II gene. Twenty-seven biopsy smears were Gram-stained and examined by the light microscope for observing H. pylori and yeast cells.
resultsFifty-four (73%) of patients were >40 year. Of 68 patients with PPI consumption record, 46 (67.6%) consumed PPI (p = 0). Comparison of patients in peptic ulcer group (12, 16.2%) with (6, 8.1%) or without (6, 8.1%) H. pylori or in gastritis group (62, 83.8%) with (25, 33.8%) or without (37, 50%) H. pylori showed no significant difference (p > 0.05). Of the 46 patients who consumed PPI, 13 (17.5%) were H. pylori-positive and 33 (44.6%) H. pylori-negative (p = 0). Ten out of twenty-seven smears showed the occurrence of H. pylori cells, including three with yeast cells. Of the 17 H. pylori-negative smears, three showed the occurrence of yeast cells only. Yeasts stained Gram-positive or Gram-negative and appeared as single or budding cells.
conclusionThe older age and PPI consumption could favor fungal colonization in the human stomach. The occurrence of a considerable number of H. pylori-positive or H. pylori-negative patients with gastritis or peptic ulcer shows that co-infection of Candida and H. pylori or infection of yeast alone could be associated with dyspeptic diseases. The occurrence of yeast cells in gastric biopsies with different Gram's reactions indicates that fungi might change their cell wall components for establishing a persistent colonization in the stomach.
