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

Mycobacterium avium subsp. paratuberculosis, the etiological agent of paratuberculosis, affects a wide range of domestic ruminants and has been suggested to be involved in Crohn's disease in humans. Most available methods for identifying and differentiating strains of this difficult species are technically demanding and have limited discriminatory power. Here, we report the identification of novel PCR-based typing markers consisting of variable-number tandem repeats (VNTRs) of genetic elements called mycobacterial interspersed repetitive units (MIRUs). Eight markers were applied to 183 M. avium subsp. paratuberculosis isolates from bovine, caprine, ovine, cervine, leporine, and human origins from 10 different countries and to 82 human isolates of the closely related species M. avium from France. Among the M. avium subsp. paratuberculosis isolates, 21 patterns were found by MIRU-VNTR typing, with a discriminatory index of 0.751. The predominant R01 IS900 restriction fragment length polymorphism type, comprising 131 isolates, was divided into 15 MIRU-VNTR types. Among the 82 M. avium isolates, the eight MIRU-VNTR loci distinguished 30 types, none of which was shared by M. avium subsp. paratuberculosis isolates, resulting in a discriminatory index of 0.889. Our results suggest that MIRU-VNTR typing is a fast typing method that, in combination with other methods, might prove to be optimal for PCR-based molecular epidemiological studies of M. avium/M. avium subsp. paratuberculosis pathogens. In addition, presumably identical M. avium subsp. paratuberculosis 316F vaccine strains originating from the Weybridge laboratory and from different commercial batches from Mérial actually differed by one or both typing methods. These results indicate a substantial degree of genetic drift among different vaccine preparations, which has important implications for prophylactic approaches.
