TRTP
Planned Treatment
Char
Cond
TRTP is a record-level identifier that represents the planned treatment attributed to a record for analysis purposes. TRTP indicates how treatment varies by record within a subject and enables analysis of crossover and other designs. Though there is no requirement that TRTP will correspond to the TRTxxP as defined by the record's value of APERIOD, if populated, TRTP must match at least one value of the character planned treatment variables in ADSL (e.g., TRTxxP, TRTSEQP, TRxxPGy).
As noted previously, at least one treatment variable is required even in non-randomized trials. This requirement is satisfied by any subject-level or record-level treatment variables (e.g., TRTxxP, TRTP, TRTA). Even if not used for analysis, any ADSL treatment variable may be included in the BDS dataset.
TRTPN
Planned Treatment (N)
Num
Perm
Numeric representation of TRTP. There must be a one-to-one relationship between TRTPN and TRTP within a study.
TRTPN cannot be present unless TRTP is also present. When TRTP and TRTPN are present, then on a given record, either both must be populated or both must be null.
TRTA
Actual Treatment
Char
Cond
TRTA is a record-level identifier that represents the actual treatment attributed to a record for analysis purposes. TRTA indicates how treatment varies by record within a subject and enables analysis of crossover and other multi-period designs. Though there is no requirement that TRTA will correspond to the TRTxxA as defined by the record's value of APERIOD, TRTA must match at least one value of the character actual treatment variables in ADSL (e.g., TRTxxA, TRTSEQA, TRxxAGy).
As noted previously, at least one treatment variable is required. This requirement is satisfied by any subject-level or record-level treatment variables (e.g., TRTxxP, TRTP, TRTA). Even if not used for analysis, any ADSL treatment variable may be included in the BDS dataset.
TRTAN
Actual Treatment (N)
Num
Perm
Numeric representation of TRTA. There must be a one-to-one relationship between TRTAN and TRTA within a study.
TRTAN cannot be present unless TRTA is also present. When TRTA and TRTAN are present, then on a given record, either both must be populated or both must be null.
TRTPGy
Planned Pooled Treatment y
Char
Perm
TRTPGy is the planned pooled treatment y attributed to a record for analysis purposes. "y" represents an integer [1-99, not zero-padded] corresponding to a particular pooling scheme. Useful when planned treatments (TRTP) are pooled together for analysis, for example when all doses of Drug A (TRTPG1=All doses of Drug A) are compared to all doses of Drug B (TRTPG1=All doses of Drug B). Each value of TRTP is pooled within at most one value of TRTPGy.
TRTPGyN
Planned Pooled Treatment y (N)
Num
Perm
Numeric representation of TRTPGy. There must be a one-to-one relationship between TRTPGyN and TRTPGy within a study.
TRTPGyN cannot be present unless TRTPGy is also present. When TRTPGy and TRTPGyN are present, then on a given record, either both must be populated or both must be null.
TRTAGy
Actual Pooled Treatment y
Char
Cond
TRTAGy is the actual pooled treatment y attributed to a record for analysis purposes. "y" represents an integer [1-99, not zero-padded] corresponding to a particular pooling scheme. Required when TRTPGy is present and TRTA is present.
TRTAGyN
Actual Pooled Treatment y (N)
Num
Perm
Numeric representation of TRTAGy. There must be a one-to-one relationship between TRTAGyN and TRTAGy within a study.
TRTAGyN cannot be present unless TRTAGy is also present. When TRTAGy and TRTAGyN are present, then on a given record, either both must be populated or both must be null.
