*

Data are mean ± SD.

Statistical comparisons of CL/F among different BMI categories are made in Table 2.

There were no statistically significant differences in the mean CL/F expressed relative to BSA or AIBW among underweight, normal, obese, and severely obese patients.

F1-153

Denotes a statistically significant difference (P < .05) for the mean CL/F in males and females within a BMI category.
