Dear bears!

Some suggestions for your To-Do list.

• NCAplots.pdf
  • In the subjects' log-plots an overlay of the fitted lambda_z lines (IMHO good practice and mandatory in Canada).
    
  • Split the mean plot: one showing the means (without SD) and mean plots of formulations with SD. Especially if the study was 'well designed' (enough data points in the area of C_max the mean plot right now is quite crowded with all the whiskers.
• NCA_PK.txt
  
  • I would add a section containing the means/SD for each formulation (by time point) - now it's not possible to cross-check with the plots.
    
  • Think about geometric means/SD; some (European) regulators prefer a plot of geometric rather arithmetic means.
    Hint: SD_geom=exp(sqrt(1/(n-1) × Sum((ln(x)-ln(x_geom))²)) - hope, I got all the parentheses right.
