Correlation of DNA methylation with the level of gene expression in the validation dataset (TCGA). a Significance of the correlation between the level of DNA methylation and expression for each gene as determined by Pearson correlation coefficient (PCC). The correlation test was run for all samples, only ER/PR-negative samples, or only ER/PR-positive samples. b Correlation test (methylation versus expression) for predictors (Table 3). c Sample level data for gene expression of predictors (Table 3). Data is presented for 22 ER/PR-negative tumors and 53 ER/PR-positive tumors. The PCC across the BCCC samples and TCGA samples (methylation versus expression) is shown on the right
