VariableName VariableLabel Type Role Note Core
STUDYID Study Identifier Char Identifier Unique identifier for a study. Req
DOMAIN Domain Abbreviation Char Identifier Two-character abbreviation for the domain. Req
TDORDER Sequence of Planned Assessment Schedule Num Timing A number given to ensure ordinal sequencing of the planned assessment schedules within a trial. Req
TDANCVAR Anchor Variable Name Char Timing A reference to the date variable name that provides the start point from which the planned disease assessment schedule is measured. This must be a referenced from the ADaM ADSL dataset e.g. ANCH1DT. Note: TDANCVAR will contain the name of a reference date variable Req
TDSTOFF Offset from the Anchor Char Timing A fixed offset from the date provided by the variable referenced in TDANCVAR. This is used when the timing of planned cycles does not start on the exact day referenced in the variable indicated in TDANCVAR. The value of this variable will be either zero or a positive value and will be represented in ISO 8601 character format. Req
TDTGTPAI Planned Assessment Interval Char Timing The planned interval between disease assessments represented in ISO 8601 character format Req
TDMINPAI Planned Assessment Interval Minimum Char Timing The lower limit of the allowed range for the planned interval between disease assessments represented in ISO 8601 character format Req
TDMAXPAI Planned Assessment Interval Maximum Char Timing The upper limit of the allowed range for the planned interval between disease assessments represented in ISO 8601 character format. Req
TDNUMRPT Maximum Number of Actual Assessments Num Record Qualifier This variable must represent the maximum number of actual assessments for the analysis that this disease assessment schedule describes. In a trial where the maximum number of assessments is not defined explicitly in the protocol (e.g. assessments occur until death) TDNUMRPT should represent the maximum number of disease assessments that support the efficacy analysis, encountered by any subject across the trial at that point in time.
