Overall design of the biomarker identification experiments. a) Metabolite profiles are originally generated by 1H NMR from five acupuncture points (Zusanli (ST36), Liangmen (ST21), Juliao (ST3), Yanglingquan (GB34), and Weizhong (BL40)). b) The metabolite profiles are grouped into 7 sets and the biomarker identification problem is designed as 7 binary classification experiments.
