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 perfringens type C causes necrotizing enteritis in humans and several other animal species. Type C isolates must produce at least beta toxin (CPB) and alpha toxin (CPA) and most strains produce several other toxins including perfringolysin O (PFO) and TpeL. However, current evidence indicates that CPB is the main virulence factor for type C infections. Most of this evidence is based upon the loss of virulence shown by isogenic type C CPB knock out mutants on cells, and also in rabbit intestinal loops and in mouse models. This virulence is regained when these mutants are complemented with the wild-type cpb gene. Many type C isolates respond to close contact with enterocyte-like Caco-2 cells by producing all toxins, except TpeL, much more rapidly than occurs during in vitro growth. This in vivo effect involves rapid transcriptional upregulation of the cpb, cpb2, pfoA and plc toxin genes. Rapid Caco-2 cell-induced upregulation of CPB and PFO production involves the VirS/VirR two-component system, since upregulated in vivo transcription of the pfoA and cpb genes was blocked by inactivating the virR gene and was reversible by complementation to restore VirR expression.
