The EF group exhibited significantly lower gestational age, birth weight, pre-extubation weight, and initial serum albumin levels (p < 0.05) but higher Day 1 fluid intake, pre-extubation FiO2, incidence of hemodynamically significant patent ductus arteriosus (PDA) (>1.5 mm), and severe IVH (p < 0.05). Here, ALB is linked to Patent ductus arteriosus.
