a Independent variables are gestational age (solid, AUC 0.85 (95% CI [0.77, 0.93])), MR-proANP (dotted, AUC 0.76 [0.65, 0.86]), CT-proET-1 (dot-dashed, AUC 0.61 [0.51, 0.72]), and a composite variable of MR-proANP and CT-proET-1 (dashed, AUC 0.72 [0.61, 0.83]). b Independent variables are those included in the NICHD BPD risk estimator (solid, AUC 0.86 [0.76, 0.95]), composite variable of NICHD BPD risk estimator variables plus MR-proANP (dotted 0.84 [0.72, 0.95]), composite variable of NICHD BPD risk estimator variables plus CT-proET-1 (dot-dashed, AUC 0.82 [0.69, 0.95]), and composite variable of NICHD plus MR-proANP plus CT-proET-1 (dashed, AUC 0.83 [0.71, 0.95]). AUC area under the curve.
