Induction of a type 2 inflammatory chronic rhinosinusitis in C57BL/6 mice.
Article in Asia Pacific allergy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Eosinophilic chronic rhinosinusitis (CRS) has been widely studied for its intractability and high recurrence rate. It can be divided into pure and mixed type 2 CRS subtypes. Mouse models that reflect pure type 2 inflammation of CRS are lacking. Objective: This study aims to establish a relatively pure type 2 CRS mouse model and compare it with 2 mixed type 2 CRS models. Methods: Three mouse CRS models were constructed: (1) aerosol ovalbumin (OVA) + aspergillus oryzae-derived protease (AP); (2) intranasal OVA + AP; (3) Intraperitoneal then intranasal OVA + AP (n = 10 per group). Nasal, lung symptoms, IgE, inflammatory cells, cytokines, and remodeling factors were evaluated. Results: Histological and micro-computed tomography showed inflammation, polyps, and opacification in all 3 experimental groups. The aerosol group had significantly increased local eosinophils and type 2 cytokines, while other types of cytokines showed no noticeable change. The nasal instillation groups also showed elevated other inflammatory factors and tissue polypoid changes were more pronounced. More severe pulmonary inflammation was observed with aerosol delivery. Conclusion: Aerosol inhalation mouse model is superior for studying nasal relatively pure type 2 inflammation and lower airway comorbidities.
