TNF and Neonatal sepsis: Therefore, we summarized relevant literature at home and abroad [34, 36, 41, 48–52] and found that the OR value of TNF-α-308G/A (rs1800629) polymorphism merged in the allele model was statistically significant (P = 0.016), indicating a significant increase in the risk of neonatal sepsis with the A allele (OR = 1.257, 95% CI: 1.044–1.513).
