CXCL8 and Neonatal sepsis: In the dominant gene model of IL-8-rs4073 study, the P-values of non-conforming HWE, conforming HWE and the overall effects were 0.937, 0.622 and 0.713, respectively, which were all greater than 0.05, indicating that IL-8-rs4073 gene polymorphism was not correlated with neonatal sepsis in the dominant gene model.
