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

The possible role of infection with Mycobacterium paratuberculosis (MAP) for the etiopathogenesis of Crohn's disease (CD) has been a matter of long-term controversy. In addition to similarities with the pathology of ruminant paratuberculosis, DNA fingerprinting confirmed the organism isolated from gut tissue, but the specificity of the immune repertoire has not as yet been evaluated. We report here on a serological study of 29 patients with CD, 20 patients with ulcerative colitis and 18 healthy control subjects, using three antigens attributed with species-specificity and selective immunogenicity following MAP infection. Antibodies binding to the 38-kD band of MAP extract were demonstrable by the Western blot technique in 57% of CD patients. Antibody levels to the 24-kD (p24BCD) cathodic bands, determined by competition ELISA using a monospecific murine antiserum, and to the 18-kD protease-resistant purified bacterioferritin, detected by standard ELISA, were significantly elevated in 53% of CD patients. However, these three antibody specificities tested in individual CD patients did not show any correlation with each other. Thus, 18% of patients were positive for all three specificities, whilst 84% had antibodies to at least one of the specific antigens. Although the exact proportion of affected patients is yet to be defined, the serological results obtained support the view that MAP infection may play an etiological role in Crohn's disease.
