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

backgroundAllergen immunotherapy (AIT) is the only disease-modifying therapeutic approach for cat allergy, though it requires at least three years of treatment and can potentially induce severe systemic reactions. Plant-derived bioparticles expressing Fel d 1 allergen (Fel d 1 eBP) have been developed as a novel therapeutic candidate for cat allergy. We aimed to investigate the allergenicity and immunogenicity profile of Fel d 1 eBP.

methodsFel d 1 eBP was synthesised in vivo in Nicotiana benthamiana and confirmed by cryo-electron microscopy and tomography. Immune modulatory properties of purified natural Fel d 1 (nFel d 1) and Fel d 1 eBP were assessed at T and B cells by flow cytometry in 12 cat-allergic subjects (CA) and 12 non-atopic controls (NAC). Single-cell RNA-seq was used to assess molecular mechanisms of Fel d 1 eBP immune skewing. The safety of Fel d 1 eBP was assessed by measuring basophil responsiveness in whole blood and further confirmed in vivo by its administration as a skin prick test (SPT) in 20 cat-allergic individuals.

resultsFel d 1 eBP was shown to be a strong inducer of Th1 cells (p < 0.05) and IL-10

conclusionsWe demonstrate that Fel d 1 eBP is hypoallergenic and demonstrates tolerogenic properties, making it a novel candidate for use in AIT for cat allergy.
