From: Metabolomic profiles of myocardial ischemia under treatment with salvianolic acid B
(a) PLS-DA score plot of the metabolic profiles obtained from 6 sham rats (â– ), 6 MI rats with no treatment (red diamond symbol), and 6 MI rats with SA-B treatment (blue triangle symbol). (R2X = 0.798, R2Y = 0.975, Q2 = 0.858, A = 4, N = 18, K = 160); (b) Validation plot obtained from permutation test (n = 100). R2 is the explained variance, and Q2 is the predictive ability of the model.
