Selective killing of the human gastric pathogen Helicobacter pylori by mitochondrial respiratory complex I inhibitors.
Article in Cell chemical biology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Respiratory complex I is a multicomponent enzyme conserved between eukaryotic cells and many bacteria, which couples oxidation of electron donors and quinone reduction with proton pumping. Here, we report that protein transport via the Cag type IV secretion system, a major virulence factor of the Gram-negative bacterial pathogen Helicobacter pylori, is efficiently impeded by respiratory inhibition. Mitochondrial complex I inhibitors, including well-established insecticidal compounds, selectively kill H. pylori, while other Gram-negative or Gram-positive bacteria, such as the close relative Campylobacter jejuni or representative gut microbiota species, are not affected. Using a combination of different phenotypic assays, selection of resistance-inducing mutations, and molecular modeling approaches, we demonstrate that the unique composition of the H. pylori complex I quinone-binding pocket is the basis for this hypersensitivity. Comprehensive targeted mutagenesis and compound optimization studies highlight the potential to develop complex I inhibitors as narrow-spectrum antimicrobial agents against this pathogen.
