When the same analysis was repeated for TMPRSS2, 2-way ANOVA revealed that TMPRSS2 expression was significantly different between CRS and control groups controlling for treatment type (2-way ANOVA p-value = 0.0378), as is consistent with the finding evident in Figure 1B, which shows a reduction in TMPRSS2 expression for CRSwNP patients as compared with control group patients. Here, TMPRSS2 is linked to chronic rhinosinusitis with nasal polyps.
