According to Liden\/Jerger\u2019s classification, the patients were divided into two groups: Type B and type C, which were defined as the tympanometry abnormal group (TAG), and the rest were classified as the tympanometry normal group (TNG).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 316 children were included in this study.

Compared to TNG, the allergen test results of fx5 (protein, milk, cod, wheat, peanut, and soybean) in TAG were higher (0.09(0.04-0.25) vs.0.14(0.05-0.45)), but eosinophilia in blood was lower (count: 0.21(0.13-0.35) vs. 0.18(0.12-0.27); ratio: 3.10 (1.90-4.70) vs. 2.50 (1.65-3.80)).
