What researchers measure

Primary outcomes

  1. AUC( Tau,ss)

    AUC tau,ss (area under the concentration-time curve of the Raltegravir in plasma at steady state over the uniform dosing interval tau) Point estimates for the intrasubject ratio of the geometric means (for treatments Test and Reference) of AUC tau,ss and their 2-sided 90% confidence intervals (CI) were calculated. The statistical model was an analysis of variance (ANOVA) on log-transformed parameters including effects for 'subject' and 'treatment'. RAL: Raltegravir , FDV: Faldaprevir

  2. Cmax ,ss

    C max,ss (maximum measured concentration of the Raltegravir in plasma at steady state) Point estimates for the intrasubject ratio of the geometric means (for treatments Test and Reference) of Cmax,ss and their 2-sided 90% confidence intervals (CI) were calculated.
