Cluster diagram of 219 tumor-specific CpG sites (rows) in 60 GC tumor samples (columns). The RPMM tree and clusters (labelled A-F) under the two major subtypes (A-C and D-F) are shown at the top of the Figure. Clinicopathological and molecular features are shown below the cluster diagram. White rectangles are cases with missing data.
