  1. Data analysis and comparison to Vermont-Oxford-Network [14] and EuroNeoNet [15] for all live-births between 501-1500 g birth-weight (without delivery room deaths (†), or that have survived until discharge home (‡)). For a definition of the listed items see [2, 4]. The first column shows the mean Swiss value. The second and third columns render the lowest (min.) and highest (max.) value achieved by one of the network units. An asterisk (*) marks where each value significantly differs from the value of the entire Swiss collective. UapH: umbilical artery pH, PDA: patent ductus arteriosus, PPH: positive pulmonary hypertension, NEC: necrotizing enterocolitis, CPAP: continuous positive airway pressure, ROP: retinopathy of prematurity, PIH: periventricular- intraventricular haemorrhage, cPVL: cystic periventricular leucomalacia, growth: rate of children born small for gestational age that have surpassed the 10th weight percentile by discharge.
