  1. Note: AUC0-t and AUCinf of subject 017 (the reference group) were calculated by removing the concentration data at the unplanned blood sampling point; AUC0-t and AUCinf of subjects 014 (the test group) and 041 (the reference group) not included in BES were re-incorporated, and AUC0-t and AUCinf of subject 070 (the reference group) were eliminated
  2. AUC0-t Area under the serum concentration–time curve (AUC) from time zero to last quantifiable concentration, AUCinf AUC from time zero to infinity, CI Confidence interval
  3. ais the 90% CI for the geometric mean ratio of T/R
