The Add Criteria window is used to add criteria to a query. The window is organized to make the process of adding criteria as intuitive as possible, and in combination with the Cohort Builder window, rather complicated sets of criteria with specific logic structures can be easily put together one criterion at a time.

In the upper left corner of the window are five buttons, which are used to select the kind of criterion to be added. The appearance of the rest of the window depends on which button is selected. Although queries may contain criteria from each of these areas, you may only add criteria from one of these buttons at a time. In other words, in order to add criteria based on both demographic and diagnosis information, you will first need to add your demographic criteria, then clicking the And or Or button on the Cohort Builder window (as appropriate), return to the Add Criteria window to add your diagnosis-based criteria.

As you use these pages to specify your criteria, your changes will not be saved until you add the criteria to the list on the Cohort Builder window. To do this, click on the Add Criteria button in the lower right corner of the window. To close the Add Criteria window and go to the Cohort Builder window without actually adding any criteria, click on the Cancel button.
