Changes in serum hypoxia-inducible factor-1α and erythropoietin in allergic rhinitis patients: Correlation with the Th inflammatory profile and disease comorbidities.
Article in International journal of immunopathology and pharmacology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
objectivesThe balance between proinflammatory IFN-γ Th1 vs. the anti-inflammatory allergy-mediating IL-4-heralded Th2 reactions is pivotal in IgE-mediated allergic rhinitis (AR). Hypoxia-Inducible Factor (HIF)-1α is inducible by hypoxia and various cytokines. HIF-1α activates different anti-pathogen and allergic immune cells. This cross-sectional study assessed the changes in serum HIF-1α and its dependent erythropoietin (EPO) levels among hospital-characterized AR patients. Type of the immune reaction, Th1 vs. Th2, was stratified based on the calculated IL-4/IFN-γ direct ratio, after being measured using specific ELISA assays.
methods147 AR patients (83 males/64 females), and age-, BMI-, and gender-matched 24 healthy controls (13 males/11 females) were sequentially enrolled at ENT Unit, Prince Muteb General Hospital, Sakaka, Saudi Arabia. Measurement of serum parameters was carried out using specific ELISA assays.
resultsContrary to the majority of previous publications, all controls and the majority of patients (
conclusionThese results confirmed a pathogenic implication for HIF-1α and IFN-γ in AR that warranted future bigger and longitudinal studies.
