Figure 2. Individual fold-error (IFE) of CLH and corrected individual fold-error (IFE’) of CL'H for the 10 CYPs in control subjects (n=105).

$\text{IFE}={10}^{\frac{1}{N}{\displaystyle \sum }\text{ log}(\mathit{\text{predicted individual value}}/\mathit{\text{observed overall mean}})}$; ${\text{IFE}}^{\prime }={10}^{\frac{1}{N}{\displaystyle \sum }\text{ log}(\text{corrected }\mathit{predictive individual value}/\mathit{\text{observed overall mean}})}$. The blue ball represents the IFE, the red ball represents the IFE’. The black horizontal lines represent the mean with 95% confidence interval.
