The incidence of complications at each gestational age (GA) group. R × 2 Chi-square test (linear-by-linear association) showed that the incidence of BPD, ROP, IVH decreased with increasing GA (all p<0.001), whereas the incidence of NEC rose up (p<0.05). There were no significant differences in the incidence of RDS, PVL, and Sepsis. RDS: Neonatal respiratory distress syndrome; BPD: Bronchopulmonary dysplasia; ROP: Retinopathy of prematurity; NEC: Necrotizing enterocolitis; IVH: Intraventricular hemorrhage; PVL: Periventricular leukomalacia. Sepsis: blood culture-positive nosocomial sepsis.*:p<0.05; ***: p<0.001
