Iron status, hepcidin, and CRP in children with endoscopically confirmed adenotonsillar hypertrophy: a controlled cross-sectional study.
Article in BMC pediatrics, 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
backgroundAdenotonsillar hypertrophy (ATH) may influence iron homeostasis through low-grade inflammation and upper airway obstruction, but findings in children remain inconsistent. This study aimed to compare hematologic, iron-related, and inflammatory parameters in school-aged children with and without endoscopically confirmed ATH.
methodsThis controlled cross-sectional study included 300 children aged 6-12 years (150 with ATH and 150 controls). Hemoglobin, serum iron, ferritin, mean corpuscular volume (MCV), C-reactive protein (CRP), and hepcidin were measured. Iron deficiency and anemia were defined according to World Health Organization criteria. Continuous variables were compared using parametric or nonparametric tests as appropriate, and categorical variables were analyzed using Pearson's chi-square test.
resultsNo statistically significant between-group differences were found in hematologic, iron-related, or inflammatory parameters. Iron deficiency was identified in 30% of children with ATH and 24% of controls (p = 0.24), whereas iron-deficiency anemia was present in 10% and 8%, respectively (p = 0.55). CRP and hepcidin levels were also comparable between groups.
conclusionIn this outpatient cohort, ATH was not associated with significant differences in routine iron indices, CRP, or hepcidin. These findings do not support routine iron evaluation solely on the basis of ATH, although targeted assessment may be considered in children with relevant clinical findings.
