PLS-DA between control and dissected aorta samples. A, PLS discrimination with the 44 genes with VIP > 1.5 – Human Broad I array (Clontech). B, PLS discrimination with 30 genes with VIP > 1.32 – Cardiovascular array (Clontech). C, PLS discrimination with 79 genes with VIP > 1.51 – Affymetrix GeneChip microarray. Horizontal axis, number of samples in the table; vertical axis, the first PLS component. Numbers next to the black squares and rhombus, refer to control "c" or dissected "p" aorta samples.
