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

Staphylococcus aureus is an opportunistic pathogen implicated in skin and soft-tissue infections and chronic inflammatory skin diseases, such as atopic dermatitis. These infections can range from mild to potentially life-threatening systemic illnesses progressing to bacteremia, endocarditis, and sepsis. Mast cells, traditionally recognized for their role in allergies, are highly abundant within the skin and are gaining recognition for their contribution to bacterial defense. Here, we discuss the role of mast cells in three models of S. aureus skin infection according to skin depth: epicutaneous sensitization, intradermal injections, and subcutaneous injections. During S. aureus skin infection, mast cells become activated and accumulate in infected skin, recognize bacterial toxins, and modulate the activity of other immune cells, including neutrophils and dendritic cells. We discuss areas of research that should be the target of future studies, such as neuroimmunology, infected excisional wounds, and risk of systemic illness. Our review aims to bring attention to the host-pathogen interaction between mast cells and S. aureus in the skin, both to encourage deeper investigation and inform the development of immunomodulatory-based therapeutics.
