Multiple Allergen Simultaneous Test for Food Allergens Cannot Screen Wheat-Dependent, Exercise-Induced Anaphylaxis and α-Gal Syndrome.

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
Screening tests for specific immunoglobulin E (sIgE) to food allergens, such as the multiple allergen simultaneous test (MAST), are widely used in patients with suspected food allergies in South Korea. We evaluated whether MAST could effectively screen wheat-dependent exercise-induced anaphylaxis (WDEIA) and α-gal syndrome (AGS). We retrospectively reviewed patients with WDEIA and AGS diagnosed with unequivocal history and positive sIgE results for omega-5 gliadin and α-gal using ImmunoCAP, respectively. The clinical manifestations and results of MAST and ImmunoCAP (sIgE to wheat for WDEIA and beef/pork for AGS) were reviewed. In the MAST and ImmunoCAP results, class 0 (<0.35 units in each test) was considered negative. Medical records of 45 patients with WDEIA and 39 patients with AGS were reviewed. For WDEIA, 37 (82.2%) of patients had a history of anaphylaxis. Among those positive for omega-5 gliadin sIgE, 39 (87.7%) and 25 (55.6%) tested positive for gluten- and wheat-sIgE using ImmunoCAP, respectively. MAST performed on 15 patients yielded positive results for wheat-sIgE in 5 (33.3%). For AGS, 23 (59.0%) of patients had a history of anaphylaxis. Among those positive for α-gal sIgE, 32 (85.7%) and 37 (96.4%) tested positive for pork- and beef-sIgE using ImmunoCAP, respectively, whereas MAST could not detect sIgE for pork and beef (0%, 0/17). MAST for sIgE to food allergens cannot screen WDEIA and AGS. The tests for sIgE to a specific component of food allergen, such as omega-5 gliadin for WDEIA and α-gal for AGS, should be used to screen WDEIA and AGS.
