Figure 4From: Reducing the risk of false discovery enabling identification of biologically significant genome-wide methylation status using the HumanMethylation450 arrayThis figure shows the distribution of standard deviation in beta values for probes on HM450K bead array, using (a) 4 blood samples and (b) 261 blood samples. In each case, the distribution of standard deviation in beta values (> = 0.10) was plotted for all probes, for probes kept for subsequent analysis (Keep probes), and for the recommended removal of probes (Discard probes).Back to article page
