Genome-wide screening of pathogenicity islands in Mycobacterium tuberculosis based on the genomic barcode visualization.

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
Mycobacterium tuberculosis (M. tuberculosis) is one of the most widely spread human pathogenic bacteria, and it frequently exchanges pathogenesis genes among its strains or with other pathogenic microbes. The purpose of this study was to screen the pathogenicity islands (PAIs) in M. tuberculosis using the genomic barcode visualization technique and to characterize the functions of the detected PAIs. By visually screening the barcode image of the M. tuberculosis chromosomes, three candidate PAIs were detected as MPI-1, MPI-2 and MPI-3, among which MPI-2 and MPI-3 were known to harbor pathogenesis genes, and MPI-1 represents a novel candidate. Based on the functional annotations of Pfam domains and GO categories, both MPI-2 and MPI-3 carry genes encoding PE/PPE family proteins, MPI-2 encodes the type VII secretion system, and MPI-3 encodes genes for mycolic acid synthesis in the cell wall. Some of these genes were already widely used in early diagnosis or treatment of M. tuberculosis. The novel candidate PAI MPI-1 encodes CRISPR-C as family proteins, which are known to be associated with persistent infection of M. tuberculosis. Our data represents a molecular basis and protocol for comprehensive annotating the pathogenic systems of M. tuberculosis, and will also facilitate the development of diagnosis and vaccination techniques of M. tuberculosis.
