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
backgroundThe CD23 molecule has an effect on the regulation of IgE synthesis, either by stimulation or inhibition. It is not yet known whether the expression of CD23 on B lymphocytes is related to the level of allergen-specific IgE antibodies in patients with atopic dermatitis.
aimThe aim of this pilot study was to evaluate the association between the expression of CD23 molecule on B cells and on their subsets (memory, naive, switched, non-switched, and total B lymphocytes) and the level of specific IgE to molecular components of mites in atopic dermatitis patients (with and without dupilumab therapy).
methodsForty-five patients suffering from atopic dermatitis were included: 32 patients without dupilumab treatment (10 men, 22 women, average age 35 years), 13 patients with dupilumab treatment (7 men, 6 women, average age 43.4 years) and 30 subjects as a control group (10 men, 20 women, average age 44.7 years). The serum level of the specific IgE was measured using the components resolved diagnostic microarray-based specific IgE detection assay ALEX2 Allergy Xplorer. In all included patients, the expression of CD23 molecule on B lymphocytes was evaluated with flow cytometry using monoclonal antibodies. For the statistical analysis of the association between expression of CD23 molecule on B lymphocytes and the level of specific IgE to molecular components of mites, we used non-parametric Kruskal-Wallis one-factor analysis of variance with post-hoc by Dunn's test with Bonferroni modification and the Spearman's rank correlation coefficient; for coefficients higher than 0.41, we report R2 (%, percent of Variation Explained).
resultsThe association between the expression of CD23 molecule on B cells and the level of specific IgE to molecular components of mites was confirmed only in patients with dupilumab therapy. In these patients, the highest association was confirmed between the level of specific IgE to Der p 20 and expression of CD23 on switched B lymphocytes (in 48.9%). In patients without dupilumab, the association between the level of specific IgE to molecular components of mites and the expression of CD23 on B cells and on their subsets is low.
conclusionFurther research is needed to fully understand the underlying mechanism of this phenomenon and its implications for the treatment of atopic dermatitis.
