CXCL8 and Neonatal sepsis: In the allele model of IL-8-rs4073 study, the P-values for non-conforming HWE, conforming HWE and the overall effects were 0.094, 0.497 and 0.087, respectively, which were all greater than 0.05, indicating that IL-8-rs4073 gene polymorphism was not associated with neonatal sepsis in the allele model.
