ArdB Protective Activity for Unmodified λ Phage Against EcoKI Restriction Decreases in UV-Treated Escherichia coli.
Article in Current microbiology, 2019. 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
Anti-restriction proteins ArdB/KlcA specifically inhibit restriction (endonuclease) activity of restriction-modification (RM) type I systems. Molecular mechanisms of ArdB/KlcA-based anti-restriction remain unknown. In this study, we quantitate effects of ArdB on protection of unmodified λ phage DNA from EcoKI restriction. After UV irradiations, which produce significant amounts of unmodified chromosomal DNA in Escherichia coli K12 cells, the protective activity of ArdB decreases. Unlike ArdB, DNA-mimicking protein Ocr retains its ability to protect the unmodified λ phage regardless of UV dose. We hypothesize that the observed decrease in ArdB protective activity in UV-treated cells is due to its binding to unmodified chromosomal DNA, which decreases effective concentrations of free ArdB molecules available for λ phage protection against type I restriction enzymes.
