FN1 and chronic rhinosinusitis with nasal polyps: In the CRSwNP group, eosinophil count was positively correlated with SNOT-22 scores (ρ = 0.5357, p = 0.0444; β = 0.001819; R2 = 0.1785), and significant positive associations were also observed between symptom SNOT-22 and TIMP-2 (ρ = 0.7496, p = 0.0009; β = 0.07088; R2 = 0.5230) as well as SNOT-22 and fibronectin (ρ = 0.5925, p = 0.0223; β = 0.1043; R2 = 0.2875) ΔΔCt values, indicating decreased expression of these remodeling genes in patients with more severe symptoms.
