Median (range) of CV% of steady state (day 7–day 35) values.

Intersubject variability calculated from CV% for all subjects within a given sample day; median (range) is from among D7, D14, D21, D28, D35 CV%s.

Intrasubject variability calculated from CV% for each subject across all his or her steady-state samples days (D7–D35); median (range) is from among all subjects CV%s. Only higher dose frequency is included due to predominance of BLQ values.
