CXCL8 and Neonatal sepsis: In the homozygous gene model of IL-8-rs4073 study, the P-values of non-conforming HWE, conforming HWE and the overall effects were 0.178, 0.643 and 0.187, respectively, which were all greater than 0.05, indicating that IL-8-rs4073 gene polymorphism was not associated with neonatal sepsis in the homozygous gene model.
