1 · What the graph read from it

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.

2 · The registry

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

Clostridium difficile PCR ribotype 106 (also identified as restriction endonuclease analysis [REA] group DH) recently emerged as the most common strain causing C. difficile infection (CDI) among US adults. We previously identified this strain predominating our pediatric cohort. Pediatric clinical CDI isolates previously characterized by REA underwent antibiotic resistance testing and whole genome sequencing. Of 134 isolates collected from children, 31 (23%) were REA group DH. We performed a comparative genomics analysis to identify DH-associated accessory genes. We identified five DH-associated genes that are associated with virulence in other bacterial species but not previously known to contribute to CDI. These genes are associated with intestinal mucosal adhesion (collagen-binding surface protein), sporulation (sporulation integral membrane protein YtvI), and protection from oxidative stress and foreign DNA (DNA phosphorothioation-dependent restriction proteins, sulfurtransferase, and DNA sulfur modification proteins). The association of these genes was validated in a cohort of 623 publicly available C. difficile sequences, 10 (1.6%) of which were monophyletic to REA group DH through in silico multilocus sequence typing and core genome phylogenetic analysis. Further investigation is required to determine the contribution of these genes to the emergence and virulence of this epidemic strain.
