The conditions listed in the leftmost column indicate the inclusion criteria for subjects on which the AUROC is computed. N indicates the number of test subjects that meet the inclusion criteria. ELBWI: <26 weeks and 400–999 g; VLBWI: 1000–1500 g. SINGLETONS: singletons with 23 ≤ GA ≤ 32. BW: birth weight; GA: gestational age.
