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

Protective CD4+ T cells against Mycobacterium bovis bacillus Calmette-Guérin (BCG), which are characterized by the ability to produce interferon-gamma (IFN-gamma), could be induced by immunization of mice with viable BCG but not with killed BCG. A high level of IFN-gamma mRNA was observed when normal spleen cells were stimulated with viable but not killed BCG. By comparing mice immunized with either viable or killed M. bovis BCG, it was found that a high level of IFN-gamma mRNA was expressed only after immunization with viable BCG. This finding prompted us to investigate the effect of neutralizing the IFN-gamma on the final generation of protective T cells against M. bovis BCG. When endogenous IFN-gamma was neutralized by administration of anti-IFN-gamma monoclonal antibody in mice immunized with viable BCG, the generation of protective T cells was significantly impaired, as revealed by the adoptive transfer of spleen T cells. The generation of BCG-specific, IFN-gamma-producing T cells was also abolished. These results clearly demonstrate that endogenous IFN-gamma actually plays a critical role in the generation of protective T cells against M. bovis BCG in vivo. Moreover, this study suggests that the lack of IFN-gamma-inducing ability is responsible for the inability of killed M. bovis BCG to induce protective T cells in mice.
