Statistical analysis
Statistical analyses were performed using SPSS software version 20 (IBM, Armonk, NY, USA). The Chi-square test was used to test the significance between the two groups. To identify the relationship between Toxocara seropositivity and asthma status, the Chi-square test and logistic regression were used to determine odds ratios (ORs) and 95 percent confidence intervals (CIs). The value < 0.05 were considered statistically significant.
