Systematic effect of copy number on methylation at CpG sites for which overall variation in methylation is small. (A) The range of standard deviation thresholds is depicted on the x-axis and the value of the correlation coefficient for the regression of copy number on small methylation changes is depicted on the y-axis for the given copy number states. (B) The range of standard deviation thresholds is depicted on the x-axis and the value of the correlation coefficient and its point-wise 95% confidence band for the regression of copy number on small methylation changes is depicted on the y-axis for each copy number state.
