In the above article [Yamazaki S, Toth LN, Black ML, and Duncan JN (2004) Drug Metab Dispos 32:398-404], the following errors should be corrected.

On page 403, the sentence “Using the CL × MLP method based on the exponent (0.910) of simple allometry, predicted CL_blood value for PNU-96391 was over-predicted by approximately 7-fold despite a high regression coefficient (0.992) across animal species” should be corrected to: “Using the CL × MLP method based on the exponent (0.910) of simple allometry, predicted CL_blood value for PNU-96391 was over-predicted by approximately 2-fold despite a high regression coefficient (0.996) across animal species”.

On page 403, the sentence “Alternatively the CL × BW method provided an under-prediction (0.4-fold) with a regression coefficient of 0.864” should be corrected to: “Alternatively the CL × BW method provided an over-prediction (1.4-fold) with a regression coefficient of 0.990”.

On page 403, the sentence “Thus the in vitro-in vivo correlation approach could predict CL_blood value more accurately than the simple allometry or the modified allometric methods” should be corrected to: “Thus the in vitro-in vivo correlation approach could predict CL_blood value more accurately than the simple allometry method”.

The authors apologize for any confusion and inconvenience caused by these errors.
