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

Tuberculosis continues to be a worldwide problem for both humans and animals. The development of tests to differentiate between infection with Mycobacterium tuberculosis or Mycobacterium bovis and vaccination with M. bovis BCG could greatly assist in the diagnosis of early infection as well as enhance the use of tuberculosis vaccines on a wider scale. Recombinant forms of four major secreted proteins of M. bovis-MPB59, MPB64, MPB70, and ESAT-6-were tested in a whole-blood gamma interferon (IFN-gamma) assay for differentiation between cattle vaccinated with BCG and those experimentally infected with M. bovis. BCG vaccination induced minimal protection in the present study, with similar numbers of animals infected with M. bovis in BCG-vaccinated and nonvaccinated groups. Following vaccination with BCG, the animals produced moderate IFN-gamma responses to bovine purified protein derivative (PPDB) but very weak responses to the recombinant antigens. Cattle from both the BCG-vaccinated and nonvaccinated groups which were M. bovis culture positive following challenge produced IFN-gamma responses to PPDB and ESAT-6 which were significantly stronger than those observed in the corresponding M. bovis culture-negative animals. IFN-gamma responses to MPB59, MPB64, and MPB70 were significantly weaker, and these antigens could not discriminate between vaccinated animals which develop disease and the culture-negative animals. The results of the study indicate that of the four antigens tested in the IFN-gamma assay, only ESAT-6 would be suitable for differentiating BCG-vaccinated animals from those infected with bovine tuberculosis.
