Figure 1From: Identification of a panel of sensitive and specific DNA methylation markers for squamous cell lung cancerSchematic representation of DNA methylation levels of 42 loci in 45 tumor and adjacent non-tumor squamous cell lung cancer cases. Black indicates high methylation levels (≥ median PMR of all, tumor and non-tumor, positive samples). Grey indicates low methylation (< median of the positive PMR values), and white indicates no detectable methylation.Back to article page
