Dear all!

From a consultant’s diary:

• Study performed in 2011 | IR formulation | very common drug | large CRO.
  
• Of course, the report stated “correlation coefficient mandatory >0.95” and “PK parameters were calculated in a blinded manner”…
  
• Maybe the pharmacokineticist was blind?
  
• PK followed a 2- or 3-compartment model in all subjects.
  
• No plots of the estimation of λ_z in the report.
  I generated the one above by trial and error to match tabulated half lives.
  
• No table showing how many and which data points were used.

What do you think?
