IgE levels correlate with Fc
Article in Frontiers in allergy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Measurement of IgE levels, skin prick tests (SPT), and basophil activation tests (BAT) are the gold standards for diagnosing Hymenoptera allergy. Currently, BAT most accurately resembles patient reactivity. However, data examining the influence of serum IgE and basophil Fc Methods: Total and specific IgE (sIgE) levels and their ratios, SPT results, high-affinity IgE receptor (Fc Results: The sIgE/IgE ratio correlated with positive SPT results at lower venom concentrations in patients with wasp allergy but not in those with bee allergy. Total IgE levels did not correlate with SPT reactivity but correlated with the total (r = 0.742, Conclusions: sIgE levels, rather than total IgE levels, can be indicative of functional test results, such as SPT and BAT, in patients allergic to wasp venom but not in those allergic to bee venom. Other activation mechanisms may account for the observed discrepancies in patients allergic to bee venom and should be explored further.
