4.2. The Strengths of This Study
RS
This study reported the characteristics of SCL changes and applied a novel analysis method to dynamic responses at the individual level. The current study revealed three distinctive tendencies for changes in the SCL. First, the change rate of the SCLs measured by both approaches depends on the initial level. In the case of participants with a low initial SCL, the difference between the amount of carotenoids intake before and after the intervention period begins is larger, which may result in a larger increase in Notably, the pattern of differences between RS and RRS in the initial tracking period suggests that Additionally, the new visualization tools and indices were proposed and confirmed for observing SCL changes from an individual rather than an average perspective. In previous studies, the effects of carotenoid-containing diets and supplement intake were confirmed by analyzing a trend of average values [Furthermore, the use of the vector fields was newly proposed to visualize the behavior of
