Fig. 2From: Short-term outcomes of extremely preterm infants at discharge: a multicenter study from Guangdong province during 2008–2017The incidence of complications in EP infants between 2008–2012 and 2013–2017. It was shown that the incidence of RDS and BPD increased during 2013–2017 when compared to 2008–2012 (p<0.001 and p<0.01, but PVL decreased (p<0.001). There were no significant differences in the incidence of ROP, NEC, IVH 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<0.01; ***: p<0.001Back to article page
