Figure 4. Associations between aberrations in DNA copy number and DNA methylation in ovarian carcinoma. (A) Frequency distribution of CNV Gain and CNV Loss. (B) Frequency distribution of CNV Gain and MetHyper. (C) Frequency distribution of CNV Gain and MetHypo. (D) Frequency distribution of CNV Loss and MetHyper. (E) Frequency distribution of CNV Loss and MetHypo. (F) Frequency distribution of MetHyper and MetHypo. Larger correlation coefficients (R values) indicate stronger correlations; the log rank P test was used.
