Plasma circulating cell-free mitochondrial DNA concentrations according to randomization to exercise intervention at all time points

	Overall (n = 99)	Usual Activity (n = 48)	Aerobic Exercise (n = 51)
Baseline	2.77 (1.23, 7.50)	3.62 (1.85, 8.33)	2.01 (1.08, 7.32)
Month 2	2.62 (1.18, 8.22)	3.08 (1.19, 8.70)	2.20 (1.09, 4.90)
Month 4	2.62 (1.18, 8.22)	2.78 (0.79, 8.29)	2.67 (1.10, 7.23)

Values are presented as medians (25th, 75th percentile) of plasma circulating cell-free mitochondrial DNA (in pM).
