Figure 6. ROC plot for (A) urinary data set (n = 31 [18non-AP/13AP]) and (B) plasma-CPMG spin−echo (n = 36 [21non-AP/15AP]). (C) Combination of 10 metabolites in total from urine (guanine at 7.67(s), hippurate at 7.54(t), 7.64(t), 7.84(d), creatine at 3.02(s) and unknown metabolites at 2.73(s), and 4.55(d), and CPMG plasma (valine at 1.04(d), alanine at 1.47 (d), and lipid compounds at 0.91(m), 1.25(m), and 1.97(m)); OPLS-DA was cross-validated from the previous ROC curve (R2 = 0.76, Q2 = 0.59, n = 29 [16non-AP/13AP]).
