Intragroup data repeatability of the GSE57691 dataset verified by Pearson’s correlation and PCA analysis. (a) Pearson’s correlation analysis of intragroup data from the GSE57691 dataset. The color represents the degree of correlation. 0< correlation <1 indicates a positive correlation, and −1< correlation <0 indicates a negative correlation. When the absolute value of a number is large, there exists a strong correlation. (b) PCA analysis of intragroup data from the GSE57691 dataset. In the scatter diagram, PC1 and PC2 represent X-axis and Y-axis, respectively, where each point is a sample. The distance between the two samples represent the difference in gene expression patterns.
