Characterization of Pana g 1, an important cause of pollen-food allergy syndrome from Korean ginseng,

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: Ginseng is a widely consumed herbal supplement. However, ginseng, especially raw ginseng, can cause allergic reactions, including pollen-food allergy syndrome (PFAS). This study aimed to identify the PFAS-causative allergen in Korean ginseng and to establish methods for its quantification. Methods: Candidate allergens were screened using genomic and transcriptomic analyses. Proteomic profiling with patient sera was performed to identify the clinically relevant allergen. A recombinant protein was generated, and its allergenicity compared with the primary sensitizer, Que ac 1, by ELISA. A two-site ELISA was developed for the quantification of the ginseng allergen using monoclonal antibodies against recombinant protein. Multiple reaction monitoring (MRM) mass spectrometry was applied for validation. Results: Genome and transcriptome analysis identified 4 candidate allergens: pathogenesis-related 10 (PR-10) protein, profilin, non-specific lipid transfer protein (nsLTP), and thaumatin-like protein. Among these, PR-10 (designated Pana g 1) was the sole allergen detected by proteomic analysis. Recombinant Pana g 1 was recognized by 4 of 5 patients. Inhibition ELISA showed stronger IgE reactivity to Que ac 1 than to Pana g 1, with marked cross-reactivity between the 2. Pana g 1 levels in ginseng extract were quantified as 4.26 μg/mg of protein by ELISA and 4.54 μg/mg by MRM in the ginseng extract. Conclusion: Pana g 1 is the major PFAS-causative allergen in Korean ginseng. Recombinant Pana g 1 shows promise as a diagnostic tool for ginseng-induced PFAS. The quantification systems established here may also support standardization of ginseng extracts and allergen monitoring.
