WebThe relationship between the pegaptanib CL/AUC and the CRCL predicted by the final model for a typical individual (random effect set to 0) is shown in Figure 3. The ratio of CL/AUC for CRCL of 30–190 mL/minute to the CL/AUC predicted for a patient with a CRCL of 80 mL/minute ranges from 0.62 to 1.53. WebThe explanation of the inter-individual variability in terms of subject-specific covariates is also of great importance.
