The fate of Helicobacter pylori phagocytized by Acanthamoeba polyphaga demonstrated by fluorescent in situ hybridization and quantitative polymerization chain reaction tests.
Article in Current microbiology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Helicobacter pylori able to express green fluorescent protein, as well as an ATCC strain, and a clinical isolate of this pathogen were evaluated for their ability to survive predation by Acanthamoeba polyphaga. Ingestion was evaluated by microscopic observation of the GFP-H. pylori and BacLight™-stained cells. Following phagocytosis, the fate of cells was assessed by fluorescent in situ hybridization with an oligonucleotide targeting H. pylori 16S rRNA and by quantitative-polymerase chain reaction (qPCR) tests with primers to 16S rDNA. Fluorescent in situ hybridization tests were inconclusive with only a small percentage of amoebae apparently containing active intracellular H. pylori. Furthermore, no increase in bacterial cells was detected by qPCR. Additional research is required to elucidate the mechanisms by which amoebae phagocytize this important bacterial pathogen.
