The data indicated that Raftlin intensity in basal cells staining in the CRSwNP and CRSwNP + SK groups was significantly higher than in the control group (Figure 1C; p = 0.0079); similarly, the Raftlin intensity in the columnar cell staining was markedly higher among the CRSwNP and CRSwNP + SK groups (Figure 1D; p < 0.001). Here, RFTN1 is linked to chronic rhinosinusitis with nasal polyps.
