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

Visceral leishmaniasis (VL) is transmitted by Leishmania-infected sand fly bites and malnutrition is a known risk factor in human VL. Models using sand fly transmission or malnutrition promote parasite dissemination. By investigating features of L. donovani-Lutzomyia longipalpis transmission to malnourished mice, we show that a comparable IL1-β-driven acute inflammation is maintained in malnourished (MN-SF) and well-nourished (WN-SF) sand fly-infected mice. However, parasite dissemination was more pronounced in MN-SF that had a significantly higher acute (P ≤ 0.001) and chronic (P ≤ 0.0001) splenic parasite burden compared to WN-SF. Compared to WN-SF, MN-SF exhibited chronic clinical symptoms (P ≤ 0.0001), neutrophilia (P ≤ 0.001), lymphocytopenia (P ≤ 0.0001), increased heme oxygenase-1 (P ≤ 0.001) and IL17-A (P ≤ 0.0001) levels, dysregulation of liver enzymes, lymph node barrier dysfunction, and augmented dysbiosis, all associated with enhanced VL severity. Combining vector-transmission and malnutrition provides an improved model to study VL pathogenesis and host defense.
