Fig. 3From: Reduced mitochondrial D-loop methylation levels in sporadic amyotrophic lateral sclerosisCorrelation between mtDNA copy number and D-loop region methylation levels in total sample (n = 114, a), in control subjects (n = 51, b), and in ALS patients (n = 63, c). The correlation between mtDNA copy number and D-loop methylation levels was analyzed using Pearson’s correlation coefficient.Back to article page
