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

Multiple pilus gene clusters have been identified in several gram-positive bacterial genomes sequenced to date, including the Actinomycetales, clostridia, streptococci, and corynebacteria. The genome of Corynebacterium diphtheriae contains three pilus gene clusters, two of which have been previously characterized. Here, we report the characterization of the third pilus encoded by the spaHIG cluster. By using electron microscopy and biochemical analysis, we demonstrate that SpaH forms the pilus shaft, while SpaI decorates the structure and SpaG is largely located at the pilus tip. The assembly of the SpaHIG pilus requires a specific sortase located within the spaHIG pilus gene cluster. Deletion of genes specific for the synthesis and polymerization of the other two pilus types does not affect the SpaHIG pilus. Moreover, SpaH but not SpaI or SpaG is essential for the formation of the filament. When expressed under the control of an inducible promoter, the amount of the SpaH pilin regulates pilus length; no pili are assembled from an SpaH precursor that has an alanine in place of the conserved lysine of the SpaH pilin motif. Thus, the spaHIG pilus gene cluster encodes a pilus structure that is independently assembled and antigenically distinct from other pili of C. diphtheriae. We incorporate these findings in a model of sortase-mediated pilus assembly that may be applicable to many gram-positive pathogens.
