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; per high-powered field).
