Missing values [Study Performance]
Dear Martin!
To quote ICH E9 (Section 5.3):
Reading the Q&A document quoted by ElMaestro in his post again I’m getting the impression members of the CHMP/PK group don’t (want to?) know this guideline…
If I anticipated events and stated a decision-tree in the protocol, there’s no need to come up with two bloody evaluations.
To quote from the movíe ‘Highlander’:
Is T/R of this subject ‘infinity’ or only ‘undefined’? Ask a mathematician.
My kind of software simply cannot deal with such a value…
❝ according to my point of view you have to define of a full analysis data set (FADS) and a per-protocol analysis data set (PADS) according to ICH E9.
❝ for FADS you have to analyze the data as they are whereas for the PADS you can specify exclusion/inclusion criteria […]

There can be only one!
What's the full data set if a subject comes up with a zero response after the reference formulation?Is T/R of this subject ‘infinity’ or only ‘undefined’? Ask a mathematician.
