From: Fresh and frozen cardiac tissue are comparable in DNA methylation array β-values, but formalin-fixed, paraffin-embedded tissue may overestimate DNA methylation levels

CpG probe data removed from sample data after in silico quality control (QC). Box plots of CpG probe data filtered and removed per sample from the raw (A) data (n = 54, duplicates of 9 patient samples in each group) and SeSAMe processed (B) data (n = 54, duplicates of 9 patient samples in each group). F = Fresh tissue, FF = Frozen tissue, FFPE = Formalin-fixed, paraffin-embedded tissue. Paired Wilcoxon’s rank-sum tests, ns = non significant, * = p < 0.05.
