Figure 1 The study design flow-diagram. CRC: Colorectal cancer; TSGH: Tri-Service General Hospital; SUMF2: Sulfatase modifying factor 2; ADAMTS5: ADAM metallopeptidase with thrombospondin type 1 motif 5; PXDN: Peroxidasin; RFS: Recurrence-free survival; PFS: Progression-free survival; OS: Overall survival.

Negative control, positive control and sterile water represent unmethylation-specific reaction, methylation-specific reaction and no contaminant reaction for polymerase chain reaction, respectively. CRC: Colorectal cancer.
