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 efficacy of Bacillus Calmette-Guérin (BCG) vaccine in preventing adult tuberculosis (TB) is highly variable. Genetic differences between BCG vaccine substrains, which can be divided into early strains and late strains based on the loss of region of difference two (RD2), may result in the variability and BCG substrains. The effect of lack of RD2 on the protective efficacy of BCG substrains against TB remains unknown. In this study, we demonstrated that CFP21 and MPT64(rCM) fusion protein, encoded by RD2 of Mycobacterium tuberculosis, could stimulate higher level of interferon (IFN)-γ in tuberculin skin test (TST)-positive healthy population than in TST-negative healthy population. Compared with naive mice challenged with virulent M. tuberculosis H37Rv, C57BL/6 mice vaccinated with pcD2164 DNA expressing rCM protein resulted in a greater decrease in the bacterial load of lung. Moreover, pcD2164 could boost the protective immunity in mice primed by BCG than BCG alone or DNA vaccination alone, as evidenced by lower bacterial load in the lung tissue and reduced lung pathology. The protection induced by BCG prime-DNA vaccine boost strategy was associated with significant increases in rCM protein-specific IFN-γ. Therefore, our results clearly indicate that the loss of RD2 has an important influence on the protective efficacy of different BCG substrains. These findings will benefit the optimal choice of BCG substrain for neonatal immunization and rational design of new vaccines for the prevention of TB.
