Correlation between age at sampling and D-loop methylation levels in total sample (n = 114, a), in control subjects (n = 51, b) and in ALS patients (n = 63, c). Correlation between age at sampling and mtDNA copy number in total sample (n = 114, d), in control subjects (n = 51, e), and in ALS patients (n = 63, f). The correlation between age at sampling and D-loop methylation levels was analyzed using Pearson’s correlation coefficient
