*The horizontal bar represents the plasma carnitine concentration (unit: μmol/L).

**The box plots indicate the medians and the inter-quartile ranges (IQR). The upper (lower) limits of the whisker plots represent the most extreme values within 1.5 IQR from the nearer quartiles (i.e., 75 percentiles or 25 percentiles).
