The test date and enrollment date will typically be recorded as property values of instances. Test date will be something like an instance of test associated with a patient record. Enrollment date would be some value off an instance of study. So this *isn't* the specified cases where the two properties are of the same individual, rather the extended case. The use case we decided on in HCLS is that where a researcher who is about to do an investigation is evaluating patient records to see who might be a candidate for a study. In that case the enrollment date would be known and the case reduces to testdate < constant. Based on this, I propose we close ISSUE-53. Should another example show up we can open a new issue. -Alan > > Jeremy >
