sIgE reactivities to allergens in patients from different age groups among male and female subjects
Binary logistic regression was used to analyze the odds ratio (OR) of the male to female subjects in each age group for positive reactions to allergens. In Figure 2, for house dust mites, German cockroach, shrimp and mold mix, the ORs were larger than 1.0 for all age groups, and most of the p values were less than 0.05. The odds of male subjects exhibiting sensitization in the age ranges 9~15 years old for three pollen mix, 6~12 years old and 40~60 years old for egg whites, 9~12 and 15~18 years old for cow’s milk, 12~18 years old for dog dander and 15~18 years old for crab were higher than those for female subjects; however, the differences were not statistically significant (P >0.05). Furthermore, the odds of male subjects in the total population exhibiting sensitization were higher than of female subjects for all nine allergens. The results were consistent with Table 1.
