Heatmaps of PHYMA signature in Asian and western datasets.

<p>(a) Training dataset of local Asian population. (b) Testing dataset of local Asian population. (c) OHSU western cohort dataset. Each row represents a methylation probe and column a sample. The level of methylation varies from green (low β) to red (high β). Tumor samples showedmore aberrant DNA methylation compared to BPH tissue. All tumor samples showed comparatively higher DNA methylation compared to the non-tumor samples.
