A study end point reflects an outcome measure of interest that is statistically analyzed to address a particular research question for the study. It typically specifies the type of assessments made; the timing of those assessments; the assessment tools used; and other details, as applicable, such as how multiple assessments within an individual are to be combined.

End points are typically associated with StudyObjectives. The property whether a study end point is primary or secondary is thus inherited from the StudyObjective that references it.
