(B) Box plots show the MIG-6 (ERRFI1) gene expression in different breast tumor subtypes in the Servant dataset of 343 primary breast cancer carcinomas, analyzed using Illumina HumanWG-6_v3 Arrays. The gene expression levels are determined using the R2 Genomics Analysis and Visualization Platform (http://r2.amc.nl). In the box plot, error bars are the 95% confidence interval, the bottom and top of the box are the 25th and 75th percentiles, the line inside the box is the 50th percentile (median), and any outliers are shown as open circles. **p < 0.01, by Student's t-test.
