Figure 4. Heat map of the six target CpG sites used in the age estimation tool in all cancer patients older than 75 years. Methylation beta values are adjusted for chronological age. The labels of the x-axis refer to the respective target CpG site in each marker. Cancer022 (called Hematologic_4) and Cancer041 (called Hematologic_12) are the two bottom rows, clustering apart from all other samples. Red colouring indicates higher beta values and blue colouring indicates lower beta values.
