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
The gram-negative anaerobic bacterium Porphyromonas gingivalis is a major causative agent of chronic periodontitis. Porphyromonas gingivalis strains have been classified into virulent and less-virulent strains by mouse subcutaneous soft tissue abscess model analysis. Here, we present the whole genome sequence of P. gingivalis ATCC 33277, which is classified as a less-virulent strain. We identified 2090 protein-coding sequences (CDSs), 4 RNA operons, and 53 tRNA genes in the ATCC 33277 genome. By genomic comparison with the virulent strain W83, we identified 461 ATCC 33277-specific and 415 W83-specific CDSs. Extensive genomic rearrangements were observed between the two strains: 175 regions in which genomic rearrangements have occurred were identified. Thirty-five of those genomic rearrangements were inversion or translocation and 140 were simple insertion, deletion, or replacement. Both strains contained large numbers of mobile elements, such as insertion sequences, miniature inverted-repeat transposable elements (MITEs), and conjugative transposons, which are frequently associated with genomic rearrangements. These findings indicate that the mobile genetic elements have been deeply involved in the extensive genome rearrangement of P. gingivalis and the occurrence of many of the strain-specific CDSs. We also describe here a very unique feature of MITE400, which we renamed MITEPgRS (MITE of P. gingivalis with Repeating Sequences).
