FIGURE 1. The local tissue level of Alt a 1 and the nasal polyp
recurrence after surgery. (A) Based on data from Alt a 1 levels diagnostic test by a ROC curve
against the recurrence group after ESS, the cut-off level of local Alt a
1 was 1.84 ng/g. (B) The Alt a 1 group was defined as those with 1.84 or
higher ng/g in NP. All others were in the low- Alt a 1 group. P values
for the comparison of local Alt a 1 level between two groups (**: p
< 0.01) (Mann-Whitney test). (C) Kaplan–Meier curves of the
recurrence-free rate at the cut-off point of local Alt a 1 levels (*: p
< 0.05) (log-rank test).FIGURE 2. Allergic inflammation of CRSwNP and the local tissue Alt a 1
level. (A) Correlation between local Alt a 1 and Alternaria-specific IgE
levels. Spearman’s rank correlation coefficient showed the relationship
between Alt a 1 and Alternaria-specific IgE levels in airway
tissues (A: rs = 0.56, P < 0.0001). (B) Patients were divided
into two groups according to the local tissue level of local Alt a 1.
(**** P < 0.0001) (Mann–Whitney U test). (C) Characteristics
by the levels of local tissue Alt a 1 for chronic rhinosinusitis groups.
P values for comparison between low- and high- Alt a 1 antigen groups.
(*p < 0.05, **** p < 0.0001, NP; nasal polyp, HPF;
