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

Chagas disease (CD), caused by Trypanosoma cruzi, leads to cardiomyopathy in approximately 20-30% of infected individuals. Interleukin-11 (IL-11) has been implicated in cardiac fibrosis, although its immunological role in this context remains unclear. This study investigated the temporal dynamics of IL-11 and its receptor, IL-11Rα, expression in the hearts of C57BL/6 mice infected with 1,000 trypomastigote forms of the Y or Colombian strains of T. cruzi. Mice were euthanized at 5, 15, 30, 60, and 120 days post-infection (dpi). Survival, parasitemia, and body and heart weights were monitored. Cardiac tissue was analyzed for parasite nests, myocarditis, collagen deposition, and expression of the IL-11 receptor alpha (IL-11Rα). Cytokine profiles were evaluated by ELISA and Cytometric Bead Array. Histopathological analysis revealed more intense myocarditis, parasite load, and collagen deposition in mice infected with the Colombian strain. Both strains induced IFN-γ, TNF-α, and IL-6 in cardiac tissue; however, IL-10, IL-4, and IL-17 were detected only in the Y strain, indicating a more balanced immune response. Despite the absence of significant IL-11 upregulation in either infection, IL-11Rα expression was progressively increased over time and positively correlated with collagen deposition. These findings suggest that IL-11Rα may play a role in cardiac remodeling and fibrosis independently of IL-11 upregulation. The results reinforce the importance of T. cruzi strain variability in disease outcome and highlight the IL-11/IL-11Rα axis as a potential target for further investigation in Chagas cardiomyopathy.
