Figure 7: An example showing how structured inclusion and exclusion critieria might be collected. Sex and age are required fields; researchers may select, Male, Female, both, or Other (for example, if the study population is intersex). (A) Users may fill in other inclusion criteria below. The field to the left is a controlled vocabulary with an “” option. Selecting “condition” will allow the user to select from a controlled vocabulary, for example, the ICD, in the field to the right. (B) The “+” button allows the user to add as many criteria as necessary. The subsequent screen, for exclusion criteria, could be similarly structured (minus the age and sex fields).
