PLS-DA plot. A The separation between the two groups is obvious, the distance within the samples is close, and the classification effect is significant. B The two dotted lines represent regression lines of R2 and Q2. R2 is (0, 0.8842) and Q2 is (0, − 0.4197). The intercept between the regression line of Q2 and the Y-axis is less than 0, which means that the research model is robust
