The concentration data were pooled across visits to identify population PK and variability parameter estimates and covariate effects. Vc/F is defined as the volume of the central (e.g. plasma) compartment and Vp/F is defined as the volume of the peripheral compartment. These parameters are dose independent. From the final model, a single value of each PK parameter was estimated for each subject, and geometric mean (95% CI) values are presented for each cohort.","dispersionType":"95% Confidence Interval","groups":[{"description":"Participants who received eltrombopag in Part 1 continued on the same dose in Part 2 unless adjustments were warranted according to the dosing guidelines.
