Only some records in PC used to calculate some parameters: Time points 8 and 9 on day 1 were not used for half-life calculations, but were used for other parameters.

Method A (Many to many, using PCGRPID and PPGRPID)

Method B (One to many, using PCSEQ and PPGRPID)

Method C (Many to one, using PCGRPID and PPSEQ)

Method D (One to one, using PCSEQ and PPSEQ)
