Metabolite Characteristics in Tongue Coating from Damp Phlegm Pattern in Patients with Gastric Precancerous Lesion
Figure 2
OPLS-DA analysis of metabolomic data of GPL damp phlegm pattern group and nondamp phlegm pattern group. (a) OPLS-DA analysis by GC-TOF-MS, (b) OPLS-DA analysis by UHPLC-QE-MS positive ion mode, and (c) OPLS-DA analysis by UHPLC-QE-MS negative ion mode. The figures of OPLS-DA illustrated that there were significant differences between GPL damp phlegm pattern group and nondamp phlegm pattern group.
