Scatter plots of β-values for sample pairs from patient C1. Each point represents the β value of one locus in this patient. For each plot, the straight line is the regression line and r2 is Pearson's correlation coefficient squared. Top: Correlation between paired FF and FFPE samples for (A) normal colon tissue and (B) tumor tissue. Bottom: Correlation between paired tumor and normal samples for (C) FF tissue and (D) FFPE tissue.
