Removal of batch effect and age effect. (a) Boxplots of BRCA1 expression before (on the left) and after (on the right) removal of batch effect, where x-axis is the batch number and y-axis is the expression level; (b) Boxplots of BRCA1 expression before (on the left) and after (on the right) removal of age effect, x-axis is age group (<50 yrs old, 50-70 yrs old and >70 yrs old) and y-axis is the expression level. In the preprocessing step, we removed batch and age effects of expression level and methylation level for every single gene.
