Fig 4. Average mitochondrial DNA copy number per cell stratified by diabetes and cognitive status.

Fig 4

Copy number of mitochondrial genomes appears to be lower in individuals with (A) diabetes (t-test p-value = 0.235, insignificant) or, (B) cognitive impairment (t-test p-value = 0.005). A larger effect was observed for cognitively impaired individuals.
