Table 2.

The PCA-X mode, OPLS-DA mode, and 999-permutation were used for multivariate exploration of clusters and trends among two groups of male and female in seven tissues.

Differential/all: differential is CL which has a significant difference, by Wilcoxon–Mann–Whitney test, in every tissue. All is all CL quantified in every tissue.
