Fig. 6From: Neonatal hair profiling reveals a metabolic phenotype of monochorionic twins with selective intrauterine growth restriction and abnormal umbilical artery flowHair metabolites with good predictive ability for the corresponding comparisons, with an area under the receiver operating characteristic (ROC) curve greater than 0.9. Pairwise comparisons are conducted between the following twin groups; a) Comparison 1: T2&3 sIUGR-S vs Control. The image on the right-hand side is a multivariate ROC curve combining 2-aminobutyric acid and cysteine; b) Comparison 2: T2&3 sIUGR-L vs Control; c). Comparison 3: T2&3 sIUGR-S vs T1 sIUGR-S. The image on the right-hand side is a multivariate ROC curve combining tyrosine, cysteine, and alanine; d). Comparison 7: T1 sIUGR-S vs Control; e). Comparison 8: T1 sIUGR-L vs Control. List of abbreviations; sIUGR = Selective intrauterine growth restriction; L = Larger twin; S = Smaller twin; T1 = Normal umbilical artery flow; T2&3 = Abnormal umbilical artery flowBack to article page
