Alterations of Microorganisms in Tongue Coating of Gastric Precancerous Lesion Patients with a Damp Phlegm Pattern

(a) PCoA diagram of the GPL group compared with the healthy control group (E: GPL group, N: healthy control group). (b) PCoA diagram of the GPL damp phlegm pattern group compared with the GPL non-damp phlegm pattern group. (C: GPL damp phlegm pattern group, D: GPL nondamp phlegm pattern group). The dots represented each sample. The abscissa and ordinate were the two characteristic values that lead to the largest difference between samples, and the main influence degree was expressed in the form of percentage. (a) The GPL group and healthy control group had a certain degree of differentiation. (b) The GPL damp phlegm pattern group and GPL non-damp phlegm pattern group had obvious differentiation.
