Scatter plots for the activity ratios for complex II+III over citrate synthase (CS) at several time points (T1, T2, and T3) compared with baseline in liver (A), skeletal muscle (B), and heart muscle (C) and the activity ratio for complex IV over CS at different time points in liver (D) and skeletal muscle (E). Individual measurements are indicated by open circles. Whiskers indicate mean ± SD. Significance between different time points is indicated by a horizontal bracket. *P < 0.05 and **P < 0.01.
