Table 3. Percent difference (95% confidence interval)^* of mtDNA copy number per one point increase in Brief Fatigue Inventory, Beck Depression Inventory, and Pittsburgh Sleep Quality Index.

Values are presented as percent difference (95% confidence interval).

^*β coefficients (95% confidence interval) for log-transformed mtDNA copy number per one point increase in Brief Fatigue Inventory, Beck Depression Inventory, and Pittsburgh Sleep Quality Index were calculated by general linear model. Then, percent difference of mtDNA copy number was calculated by multiplying 100 to the value of (exponentiated β coefficient-1). ^†Adjusted by age, sex, body mass index, smoking status, alcohol intake, exercise, and comorbidity. ^‡P<0.05.
