Subject: Blank data points
Hello,
I have a sparse data set of drug concentrations in patients (2-3 samples per patient). This includes blank plasma samples (time=0) also in about 50% of the population(total number of patients=120). I would like to know if all these blank sample data also should be included in the population analysis or it is valid to exclude them.
Thanks,
Raj
