Figure 3.

African American CRCs have fewer chromosome arms affected by cnLOH than White CRCs. Number of chromosome arms affected by cnLOH in each CRC (expressed as percentage of total chromosome arms) is represented as a dot on the graph, stratified into CCCC African Americans (left, grey), TCGA African Americans (middle, green), and TCGA Whites (right, purple). Boxes represent 25^th, 50^th, and 75^th quartiles, while whiskers represent 1.5 interquartile range for that data series. Note that many samples had no arms affected and that the maximum percentage of arms affected for any individual was < 40%.
