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

Antibiotics are urgently needed against drug-resistant bacterial infections. We report synthetic peptides with dual antimicrobial and immunomodulatory action. These peptides activate the human Mas-related G protein-coupled receptor-X2 (MRGPRX2) and its mouse ortholog, Mas-related G protein-coupled receptor-B2 (MRGPRB2), while directly killing bacteria. Unlike traditional MRGPRX2 agonists, these peptides contain protease-resistant d-amino acids, enhancing their stability. In a mouse infection model, the peptides demonstrated antimicrobial efficacy, and activated human MRGPRX2 but not its G165E missense variant. They also stimulated tumor necrosis factor alpha (TNF-α), C-C motif chemokine ligand 3 (CCL3), and interleukin-8 (IL-8) release in human mast cells via MRGPRX2 and triggered degranulation in mouse mast cells via MRGPRB2. The peptides increased vascular permeability, promoted neutrophil and monocyte recruitment, and cleared
