An instance of the OperationResult is created for each individual "statistic" value generated by the analysis. There will be at least 1 instance for each statistical operation defined for the method associated with the analysis (i.e., specified in the methodId attribute of the analysis). For analyses with at least one 1 grouping factor that is marked as generating a result for each group (the the resultsByGroup attribute of the OrderedGroupingFactor class has a value of "true"), there will be 1 instance for each combination of statistical operation and groups within the results-by-group groupingsgrouping factors. For example:

  • In a simple analysis for "Count of subjects in the safety population", where the associated analysis method only has a single operation (i.e., "Count of subjects") and there are no results-by-group groupingsgrouping factors, there will only be 1 result value (i.e., only one instance of the OperationResult class).
  • In an analysis for "Summary of subjects by treatment and sex", where the analysis method has 2 operations (i.e., "Count of subjects" and "Percent of subjects") and there are 2 results-by-group groupingsgrouping factors:
    • "Treatment" with 3 groups: "Placebo", "Drug A", and "Drug B"
    • "Sex" with 2 groups: "Male" and "Female"

There will be a total of 12 individual result values (i.e., 12 instances of the OperationResult class); 1 for each combination of operation, treatment group and sex group:

In each instance of the OperationResult class:

  • The operationId attribute contains the identifier value for the operation that generated the result (i.e., 1 of the operations defined in the method associated with the analysis).
  • The resultGroups attribute may contain references to the grouping factor(s)/group(s) associated with the result (see below).
  • The rawValue attribute contains raw result value generated by the statistical operation, with no formatting or rounding applied.
  • The formattedValue attribute contains the result value formatted according to the pattern specified in the resultPattern attribute of the operation referenced by the operationId attribute value.

The resultGroups attribute is used to associate the result value with any grouping factors defined for the analysis. The association with each grouping factor is represented as an instance of the ResultGroup class, in which:

  • The groupingId attribute contains the identifier value for the subject or data grouping factor.
  • For results-by-group grouping factors, either:
    • The groupId attribute contains the identifier value for a predefined group within the grouping factor, or
    • For data-driven grouping factors (where the value for the dataDriven attribute of the grouping factor is "true") which do not have predefined groups, the groupValue value contains a one of the data values from the grouping variable.
