Concentration of Th1 and Th2 cytokines in nasal polyps, ITs and bronchial biopsies in CRSwNP patients.

<p>A: Th1 cytokines. B: Th2 cytokines. Log transformed data, concentrations in pg/mL. NP = nasal polyp, BB = bronchial biopsy, IT = inferior turbinate. P-values represent comparison by a paired Wilcoxon signed rank test. Both CRSwNP patients with and without asthma are included in this analysis. All Th2 cytokines were increased in the nasal polyps compared to the bronchii; this difference was not seen for Th1 cytokines.
