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

backgroundIn alpha-gal syndrome (AGS), IgE antibodies form against the glycan galactose-α-1,3-galactose (alpha-gal) in mammal products rather than food proteins. Alpha-gal glycolipids and glycoproteins activate human basophils sensitized with AGS plasma in an IgE-dependent fashion. However, it is unknown whether alpha-gal specific IgE (sIgE), independent of other blood proteins, is sufficient for mediating basophil and mast cell activation.

objectiveWe sought to determine whether alpha-gal antigens could activate passively sensitized rat basophilic leukemia (RBL) SX-38 cells, which express human IgE receptors and are commonly used to model allergen/IgE-mediated mast cell activation in food protein allergy.

methodsUsing the clustered regularly interspaced short palindromic repeats technology, we created a novel, alpha-gal-deficient RBL cell line, alpha-gal knockout RBL SX-38, passively sensitizing cells with sera from AGS donors or with novel alpha-gal sIgE clones, and then stimulated with alpha-gal glycoproteins. To assess effector cell activation, we measured cell surface expression of activation marker CD63 by flow cytometry and mediator release through β-hexosaminidase release assays.

resultsAfter alpha-gal antigen stimulation, the percentage of CD63

conclusionsCertain alpha-gal-specific human IgE clones may partially activate allergic effector cells independent of antigen, potentially lowering thresholds for subsequent alpha-gal-induced or antigen-independent allergic effector cell degranulation. This may affect duration and severity of allergic symptoms in patients with AGS.
