ANMETH is a "record qualifier" according to Model 2.0 so technically we don't need to add the METHOD variable into PP. There would only be one valid value of PPMETHOD anyway = CALCULATION. (Confirm with Fred)
Rows 4-5 can the values in PPANMETH also in PPCAT? (Because PPCAT is blank)
Should ANMETH be only used for named formulas like how LB is using it?
Review suppPP dataset makes sure it looks ok
The example below shows how to represent various PK analysis parameters at multiple dose, steady state condition.
Rows 1-3:
Show the "AUC from T1 to T2" measurements for Drug Parent (Row 1), Drug Metabolite 1 (Row 2) and Drug Metabolite 2 (Row 3).
Row 4:
Shows the "Ratio AUC" measurement of Drug Parent to Drug Metabolite 1. Instead of pre-corrdinating "Ratio AUC of Drug Parent over Drug Metabolite 1" all into the PPTEST, PPANMETH is used to describe the numerator (Drug Parent, PPSEQ 1) and the denominator (Drug Metabolite 1, PPSEQ2) values that contribute to the Ratio AUC calculation in PPTEST. This post-coordination approach liberates the PPTEST variable from having to house hyper-specific, pre-coordinated PK parameter values.
Row 5:
Shows the "Ratio AUC" measurement of Drug Parent to Drug Metabolite 2. Instead of pre-corrdinating "Ratio AUC of Drug Parent over Drug Metabolite 2" all into the PPTEST, PPANMETH is used to describe the numerator (Drug Parent, PPSEQ 1) and the denominator (Drug Metabolite 2, PPSEQ3) values that contribute to the Ratio AUC calculation in PPTEST. This post-coordination approach liberates the PPTEST variable from having to house hyper-specific, pre-coordinated PK parameter values.
Rows 6-7:
Show AUC Infinity Obs and AUC Infinity Pred for the DRUG PARENT. Both are calculated using the LIN-LOG TRAPEZOIDAL METHOD which is in PPANMETH.
