Comparison of mtDNA content between patients with and without the 4, 977-bp mtDNA deletion. mtDNA contents in tumor and non-tumor tissues from 20 patients with 4,977 bp deletion and 18 age- and gender-matched patients without the deletion were compared (tumor, closed circle/triangle; non-tumor, open circle/triangle; circle, with common deletion; triangle, without common deletion). The solid lines represent the mean values. All p values were derived from independent-samples T test analysis.
