SOPitis? [Software]
Dear Fabrice,
I wonder if you are not overdoing standardization. I am definitely a friend of laying down applied methods in the protocol, which – contrary to SOPs – are reviewed by the IEC and approved by an agency, but I think that you are going a little bit too far here. Descriptive statistics of concentrations are as relevant in BE as the listing of anthropometric data of subjects.
I would be reluctant to use the term “bias”, since we don’t have good (any?) evidence of the underlying distribution of concentrations. Which location parameter should we use? The arithmetic or geometric mean, the median (see this post)?
BTW, most (all?) people connect data points by straight lines. Does that make sense (see this post)?
Sampling too early would ring my alarm bell concerning the proper performance of the clinical part.
