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

Brucellosis, a disease caused by the gram-negative bacterium Brucella spp., is a widespread zoonosis that inflicts important animal and human health problems, especially in developing countries. One of the hallmarks of Brucella infection is its capacity to establish a chronic infection, characteristic that depends on a wide repertoire of virulence factors among which are immunomodulatory proteins such as PrpA (encoding the proline racemase protein A or hydroxyproline-2-epimerase), involved in the establishment of the chronic phase of the infectious process that we have previously identified and characterized. We report here that, in vivo, Brucella abortus prpA is responsible for an increment in the B-cell number and in the specific antibody response and that these antibodies promote cell infection. We additionally found that Brucella alters the cytokine levels of IFN-γ, IL-10, TGFβ1 and TNFα during the acute phase of the infectious process in a prpA dependent manner.
