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

Isogenic mutants of Streptococcus gordonii DL1 (Challis) in which the genes encoding high-molecular-mass cell surface polypeptides CshA and/or CshB were inactivated were deficient in binding to four strains of Actinomyces naeslundii and two strains of Streptococcus oralis. Lactose-sensitive interactions of S. gordonii with A. naeslundii ATCC 12104 and PK606 were associated with expression of cshA but not of cshB. Lactose-insensitive interactions of S. gordonii with A. naeslundii T14V and WVU627, and with S. oralis C104 and 34, were dependent on expression of cshA and cshB. S. gordonii DL1 cells bound to immobilized human fibronectin (Fn), but not to soluble Fn, in a dose-dependent manner, and binding was noninhibitable by heparin. S. gordonii cshA and cshB mutants were also deficient in binding to immobilized human Fn. Antibodies to an NH2-terminal nonrepetitive region (amino acid residues 42 to 886) of recombinant CshA inhibited binding of S. gordonii DL1 cells to A. naeslundii T14V and PK606 and to immobilized Fn. Conversely, antibodies to an amino acid repeat block segment of the COOH-terminal domain (amino acid residues 2026 to 2508) were not inhibitory to adherence. Assays using CshA-specific antibodies revealed that surface expression of CshA was reduced in cshB mutants. The results suggest that CshA acts as a multifunctional adhesin in S. gordonii and that major adhesion-mediating sequences are specified within the nonrepetitive NH2-terminal region of the polypeptide.
