- aExpressed genes, FPKM > 0.25; non-expressed genes, FPKM < 0.05. Parentheses indicate percentage of total in each CpG context category.
- bUnique ageCGs/genes had q < 0.05 from linear regression results in one tissue and q > 0.5 for the same affiliated gene in the other three tissues.
- cShared ageCGs/genes had q < 0.05 in all four tissues.
- dResulting P-values from Fisher’s exact tests between the number of unique and shared, expressed or non-expressed ageCGs/genes within tissues.
- *Significant P-values meet Bonferroni correction for multiple testing.
