Escherichia coli phage-inducible chromosomal island aids helper phage replication and represses the locus of enterocyte effacement pathogenicity island.

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
In this study, we identify and characterize a novel phage-inducible chromosomal island (PICI) found in commensal Escherichia coli MP1. This novel element, EcCIMP1, is induced and mobilized by the temperate helper phage vB_EcoP_Kapi1. EcCIMP1 contributes to superinfection immunity against its helper phage, impacting bacterial competition outcomes. Genetic analysis of EcCIMP1 led us to uncover a putative transcriptional repressor, which silences virulence gene expression in the murine pathogen Citrobacter rodentium. We also found a putative excisionase encoded by EcCIMP1 which paradoxically does not promote excision of EcCIMP1 but rather supports excision of the helper phage. Another putative excisionase encoded by a presumed integrative conjugative element can also support the excision of vB_EcoP_Kapi1, demonstrating crosstalk between excisionases from multiple classes of mobile genetic elements within the same cell. Although phylogenetically distant from other characterized PICIs, EcCIMP1 and EcCIMP1-like elements are prevalent in both pathogenic and commensal isolates of E. coli from around the world, underscoring the importance of characterizing these abundant genetic elements.
