Only some records in PC used to calculate parameters: Time point 5 was excluded from Tmax, 6 from Cmax, and 11 and 12 from AUC.
Method A (Many to many, using PCGRPID and PPGRPID)
Day 8 relationships are the same as those shown in Example 1.
RELID 1
Indicates that Tmax used records with PCGRPID values DY1DRGX_A, DY1DRGX_C, and DY1DRGX_D.
RELID 2
Indicates that Cmax used records with PCGRPID values DY1DRGX_A, DY1DRGX_B, and DY1DRGX_D.
RELID 3
Indicates that AUC used PCGRPID values DY1DRGX_A, DY1DRGX_B, and DY1DRGX_C.
RELID 4
Indicates that all other parameters (PPGRPID = OTHER) used all PC time points: PCGRPID values DY1DRGX_A, DY1DRGX_B, DY1DRGX_C, and DY1DRGX_D.

Note that in this RELREC table, the single records in rows 1, 3, 5, 7, and 9, represented by their --GRPIDs (Tmax, DY1DRGX_C, Cmax, DY1DRGX_B, AUC) could have been referenced by their SEQ values, as both identify the records sufficiently. At least 2 other hybrid approaches would have been acceptable as well: using PPSEQ and PCGRPIDs whenever possible or using PPGRPID and PCSEQ values whenever possible. Method D uses only SEQ values.
Method D (One to one, using PCSEQ and PPSEQ)
Day 8 relationships are the same as those shown in Example 1.
RELID 1
Indicates records with PCSEQ values of 1-4 and 6-12 are related to the record with a PPSEQ value of 1.
RELID 2
Indicates records with PCSEQ values of 1-5 and 7-12 are related to the record with a PPSEQ value of 2.
RELID 3
Indicates records with PCSEQ values of 1-10 are related to the record with a PPSEQ value of 3.
RELID 4
Indicates records with PCSEQ values of 1-12 are related to the records with PPSEQ values of 4-7.
