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

Background and Aims: Chagas disease, caused by Methods: A total of 31 dogs with Results: Blood parasite burden and electrocardiographic (ECG) recordings as primary outcomes showed that therapeutic vaccination led to a significant decrease in parasite burden, prevented/stopped cardiac alterations and was safe. This clinical benefit was mediated by major changes in T cell activation and T cell receptor (TCR) repertoire, while antibody responses were minimally affected. In addition, vaccination also reprogrammed the ongoing trained immunity to reduce inflammation, suggesting a complex interplay between innate and T cells in its mechanism of action. Conclusions: These results provide a strong support for the further development of a veterinary vaccine based on these antigens as well as a human therapeutic vaccine to prevent the progression of chronic cardiac disease from
