Development of a Dot-Blot Assay for the Detection of Mould-Specific IgE in the Belgian Population.

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
backgroundData on mould sensitization in the general population are scarce and mostly on Aspergillus fumigatus, Alternaria alternata and Cladosporium herbarum.
objectivesTo validate a dot-blot assay for the detection of specific IgE and evaluate the prevalence of mould sensitization in a healthy population.
methodsThe dot-blot assay was validated against the CAP test. Sensitization rate to ten common indoor and outdoor mould species in 344 serum samples was calculated. For each serum with more than one reactivity, the "major sensitization" defined as the strongest response against a single mould species was calculated.
resultsIntra- and inter-assay variations were both below 20%, and the positivity threshold of the test was of 0.418 kU/L for A. fumigatus. Correlation with CAP results was strong. The overall prevalence of sensitization was 32.8%, and the commonest sensitizations were against A. alternaria, A. flavus and A. niger (around 15%). The most frequent "major reactivities" were against A. niger and A. alternata (20-30%). In 25.1% of the samples, "major reactivities" were directed against a group of moulds commonly found indoor (Penicillium spp., Aspergillus versicolor, Cladosporium sphaerospermum and Cladosporium cladosporioides).
conclusionsThe dot-blot assay was validated for the detection of mould-specific IgE. In the general population, sensitization to indoor species was common and accounted for 25% of overall mould sensitizations.
