This example shows the definition of 3 analysis sets, each of which is represented as an instance of the AnalysisSet class within the analysisSets attribute of the reporting event. The first 2 analysis sets are simple conditions based on a single specified selection value for a population flag variable, and the third is a compound expression that combines the conditions defined for the first 2 analysis sets. The sponsor chose to include a description and label for each of the analysis sets.
Lines 2-13: | Show the "Safety Population" analysis set defined as a simple condition that specifies that the value of the SAFFL variable in the ADSL dataset is equal to "Y". This condition could be expressed as:
|
Lines 14-25: | Show the "Region X Population" analysis set defined as a simple condition that specifies that the value of the RGXFL variable in the ADSL dataset is equal to "Y". This condition could be expressed as:
|
Lines 26-40: | Show the "Region X Safety Population" analysis set defined as a compound expression that uses the "AND" logical operator to combine the conditions specified for the "Region X Population" and "Safety Population" analysis sets (meaning that only subjects meeting both conditions are included in the analysis set ). When the references to the other analysis sets are resolved, this expression could be expressed as:

These analysis sets could be represented in tabular form as shown in the following table where:
- Each represents an instance of either the AnalysisSet class or, for subclauses in a compound expression, the ReferencedAnalysisSet class.
- The values of the id, name, description, and label attributes of the "AnalysisSet_RGXSAF" instance of the analysis set class have been propagated onto all rows representing subclauses defined within the analysis set.
- The logicalOperator attribute from the CompoundSetExpression class, the subClauseId attribute from the ReferencedAnalysisSet class, and all the attributes from the WhereClauseCondition class are represented as separate columns.
- Cells highlighted in yellow contain derived values: the values in the dataset, variable, comparator and value columns have been retrieved from the definitions of the analysis sets using the identifier values specified in the subClauseId attribute.
