Figure 5: PCA and PLSDA scores in Qi deficiency and nonQi deficiency groups. Note. (a) The top five PCs overview for CPMG; (b) the five PCs overview for LED; (c) and (e) 2D and 3D score plot of PLSDA for CPMG; (d) and (f) 2D and 3D score plot of PLSDA for LED. In (c) and (d), nqd = nonQi deficiency group, qd = Qi deficiency group. In (e) and (f), Red triangle = nonQi deficiency group; green triangle = Qi deficiency group. For CPMG, R ^{2}X = 0.42634, R ^{2}Y = 0.86034, and Q ^{2} = 0.88. For LED, R ^{2}X = 0.38967, R ^{2}Y = 0.8136, and Q ^{2} = 0.9375.
