Population characteristics based on PCA matrix. The multivariate PCA matrix was used to localize the samples based on different stratifications: (a) case or control, (b) DRC (high and low), (c) tumor grade, and (d) BC subtypes. (e) PCA scree plot for the relative miRNAs expression of 26 BC cases and 27 controls. (f) Loading plot of miRNAs illustrating the PC1 and PC2 contribution to the variation among samples.
