Subcutaneous Allergen Immunotherapy With Hypoallergenic Bet v 1 Compared to Conventional Extract: Poorer Blocking Antibody Capacity Dominated by IgG
Trial report in Allergy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundHypoallergenic recombinant fold-variants of major allergens have been suggested as safer and more effective AIT candidates. The Bet v 1-fold variant BM41, with confirmed preclinical hypoallergenicity and increased immunogenicity, was proposed for the treatment of birch pollen allergy.
methodsWe performed a 6-month randomized, double-blind, placebo-controlled first-in-human clinical trial with BM41, a licensed birch pollen extract-based treatment, as the active comparator (AC), and placebo (n = 16, n = 16, and n = 15, respectively). The primary endpoint was safety. Secondary outcomes were Bet v 1-specific (s)IgE, IgG, IgG
resultsDespite SPT-confirmed hypoallergenicity (~50% compared to natural Bet v 1), more adverse events occurred in response to BM41. Although similar sIgG and sIgG
conclusionPreclinically established hypoallergenicity of BM41 did not result in a lower number of adverse events. The reduced induction of sIgG
