  • aUsing the DMRs identified in HR rat versus LR rat methylome comparisons (threshold: p < 0.05), the profile of IR rats, which are created by cross-breeding the HR/LR lines, was contrasted with HR and LR profiles (HR/IR or LR/IR comparisons). The paired outcomes are shown in a 2 × 2 contingency table. Because more LR/IR DMRs were observed than HR/IR DMRs (172 vs 122), the IR methylome profiles have a tendency to be more similar to HR (p = 0.004267; McNemar's χ2 test).
