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 ability of the adaptive immune system to restrict Mycobacterium tuberculosis (Mtb) is impeded by activated Foxp3(+) regulatory T (T reg) cells. The importance of pathogen-specific T reg cells in this process has not been addressed. We show that T reg cell expansion after aerosol Mtb infection does not occur until Mtb is transported to the pulmonary lymph node (pLN), and Mtb-specific T reg cells have an increased propensity to proliferate. Even small numbers of Mtb-specific T reg cells are capable of delaying the priming of effector CD4(+) and CD8(+) T cells in the pLN and their subsequent accumulation in the lung, the primary site of infection. This delay likely prolongs the initial phase of bacterial expansion and explains the higher bacterial burden observed in these mice. Thus, T reg cells recognizing Mtb-derived antigens specifically and potently restrict protective immune responses during tuberculosis.
