The Immunology of Alpha-Gal Syndrome: History, Tick Bites, IgE, and Delayed Anaphylaxis to Mammalian Meat.
Review in Immunological reviews, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
The primary features of the alpha-gal syndrome (AGS) are (i) The IgE ab that are causally related to anaphylaxis with infusions of Cetuximab are specific for galactose alpha-1,3-galactose. (ii) In the USA, this IgE ab is induced by bites of the tick Amblyomma americanum. (iii) The anaphylactic reactions to food derived from non-primate mammals are delayed in onset by three to five hours. A further important fact is that all humans make a "natural" response to alpha-gal which includes IgM, IgG, and IgA, but not IgE. The clinical features of AGS are recognized in many parts of the world, but different species of ticks are involved. The immune response to tick bites includes T cells specific for tick protein, while IgE producing B cells appear to be derived from B cells specific for IgM or IgG. With repeated tick bites, the T cells develop a strong Th2 signal with IL-4 and IL-13 This obviously relates to IgE production, but may also be relevant to itching after tick bites which can last for weeks. The current hypothesis about the cause of the delayed reactions is based on the time that it takes to digest glycolipids from meat to LDL. The management of AGS symptoms is based on the avoidance of food derived from mammals; however, the only thing that can allow IgE to decrease is avoidance of tick bites.
