Fig. 5From: A metabolic exploration of the protective effect of Ligusticum wallichii on IL-1β-injured mouse chondrocytesMultivariate data analysis. Pathway a PCA directly suggests a variation of metabolites among control, IL-1β-treated, and IL-1β + L. wallichii-treated group. Each dot in the panel indicates the replicate analysis of samples. b, c S-plot generates from OPLS-DA. Predictive component p [1] and correlation p(corr) [1] explain the difference between control and IL-1β, and IL-1β and IL-1β + L. wallichiiBack to article page
