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

We have developed a system in which a foreign antigen replaces nearly all of the surface-exposed region of the fibrillar M protein from Streptococcus pyogenes and is fused to the C-terminal attachment motif of the M molecule. The fusion protein is thus expressed on the surface of Streptococcus gordonii, a commensal organism of the oral cavity. The antigen chosen to be expressed within the context of the M6 molecule was the E7 protein (98 amino acids) of human papillomavirus type 16. Stable recombinant streptococci were obtained by integrating genetic constructs into the chromosome, exploiting in vivo homologous recombination. The M6-E7 fusion protein expressed on the S. gordonii surface was shown to be immunogenic in mice. This is the first step in the construction of recombinant live vaccines in which nonpathogenic streptococci as well as other gram-positive bacteria may be used as vectors to deliver heterologous antigens to the immune system.
