The Inhibitory Effect of Mouse Gastric DNA on Amplification of Helicobacter pylori Genomic DNA in Quantitative PCR
Article in Iranian biomedical journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Quantitation of Helicobacter pylori (Hp) in the gastric tissue is essential for assessment of vaccination/therapeutic regimens. Materials & Results: Here, the inhibitory effect of mouse gastric DNA (MgDNA) on amplification of Hp genomic DNA (HpDNA) was evaluated by spiking HpDNA with serial dilutions of MgDNA, which yielded concentrations of >10 ng/µl and >0.63-10 ng/µl of MgDNA, as inhibition and interference zones, respectively. Mice were then inoculated with varying doses of Hp and assessed at the inhibition-free concentration of 0.63 ng/µl. The average Hp copy numbers per microgram of gastric tissue discriminated mice having received high vs. low dose inoculums (p < 0.001). Secondly, Hp copy numbers were quantitated in immunized mice, which demonstrated significantly lower numbers, in reference to controls (p = 0.006). Conclusion: Our method, bypassing the inhibition and/or interference imposed by MgDNA, was able to quantitate gastric tissue-colonizing Hp, segregating mice inoculated with low vs. high doses of Hp, as well as those immunized from controls.
