Fig. 1: AR expression according to HR/HER2 subtype, intrinsic subtype, histological grade, and nodal status in I-SPY 1.
From: Androgen receptor gene expression in primary breast cancer

Box plots show median-centered normalized AR gene expression levels stratified by a HR/HER2 status; b expression-based intrinsic subtype; c histological grade; and d nodal status. The line within boxes indicate the median AR expression; and boxes span the inter-quartile range (IQR). Whiskers span 1st quartile −1.5 × IQR and 3rd quartile +1.5 IQR; and outliers are represented by points.
