ccf-mtDNA 8oxoG variant count by cognitive phenotype and sex in each population. (a) Grouped bar graph of log transformed plasma 8oxoG variant count by cognition and sex in MAs testing for cognition × sex interaction via two-way ANOVA (n = 57, P = 0.3633, F-statistic = 0.8408, df = 53). (b) Grouped bar graph of log transformed plasma 8oxoG variant count by cognition and sex in NHWs testing for cognition × sex interaction via two-way ANOVA (n = 65, P = 0.6476, F-statistic = 0.2110, df = 61). Error bars represent standard error of the mean.
