Figure 1From: Integrative network analysis of TCGA data for ovarian cancer 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.Back to article page
