Figure 2: A longitudinal cross-over evaluation between ubiquinol or vehicle supplementation visualized the correlation of high ubiquinol – low ubiquinone with social motivation by BOUQEUT. a. The trajectories of two marmosets, A (female) and B (male) through four times of behavioral tests in a 3D time space b. The 16 factor loading positive vectors projected from the average center (see more detail in text) c. The top view of the 3D time space at each time point level with distribution ellipses of A and B d. The raw data of behavioral and physiological parameters during a longitudinal cross-over ubiquinol test. Behavior test was performed four times and plasma ubiquinol/ubiquinone was measured at 9 time points over 11 weeks. The left panel is for the subject A and the right for the subject B. In the correlation analysis, the plasma data at the behavior test time point was used.
