Figure 4.
The correlation between 15-LOX-1 mRNA expression and the number of eosinophils in NP tissues (all CRS subjects, (A); ECRS subjects, (B)). The correlation between 15-LOX-1 and periostin mRNA expression in nasal tissues (all subjects, (C); ECRS subjects, (D). The correlations were assessed using a Spearman rank correlation test. ** p < 0.01, and **** p < 0.0001.
