NEAT1 and chronic rhinosinusitis with nasal polyps: qPCR analysis confirmed that miR-199-3p was significantly downregulated in CRSwNP tissues compared to controls (Figure 4D), and Pearson correlation analysis showed a strong inverse correlation between NEAT1 and miR-199-3p expression (R = −0.9043, p = 0.0001) (Figure 4E).
