Dear all,

another recent dataset. The SmPC of the reference states median t_max with 2.75 h.

Nonparametric (planned) evaluation:
Median T_max (ref) 4.8333 h
Hodges-Lehmann estimate -0.1042
92.66% CI: -1.2416, +1.2583 [AR: -0.8120,+0.8120] not BE

Partial AUC truncated at SmPC's (labeled) median t_max (EU?)
GMR: 85.87%
90% CI: 69.15%, 106.6% not BE
CV_intra: 31.38%

Partial AUC truncated at median t_max (ref) from study USA (EU?)
GMR: 82.43%
90% CI: 73.28%, 92.71% not BE
CV_intra: 16.75%

Partial AUC truncated individually at t_max (ref) - Canada
GMR: 81.21%
90% CI: 70.61%, 93.40% not BE
CV_intra: 19.98%

CV_intra in the study were 9.24% (AUC_t) and 19.6% (C_max). All methods agree, but variability of partial areas were quite high (I've performed 13 studies with this formulation, so we had enough sampling points planned to properly characterize the peak).
