Figure 1.
Scatter plots of QMSP analysis of candidate gene promoters, Kif1a, DCC, RARb, and NISCH. The samples were categorized as unmethylated or methylated based on detection of methylation above a threshold set for each gene (horizontal bar). Red dots represent subjects with no disease (controls) or stable disease (GGO and lung cancers) upon follow-up (2–6 years). Green dots represent patients who progressed to advanced disease and are deceased. White dots represent subjects with no follow-up.
