At Month 0, CSD infants exhibited a higher number of HGT events than VD infants. However, the numbers converged around Month 2 and remained comparable until Month 9, with no significant differences between groups (p > 0.05).

Functional analysis revealed that HGT in VD enriched genes related to carbohydrate metabolism and immune responses, whereas CSD was enriched for metabolic processes and biofilm formation. Additionally, HGT events were associated with Neonatal Intensive Care Unit Admission and diet transitions.
