WHI data section of whi.org. Specimen volume data is refreshed on a weekly basis.
How do I find participants who are in study A and are also in study B? or Can I use the same criteria more than once in a query?
When you pick more than one item in a "select many list" style criteria like the ancillary study criteria, it defaults to combining those selections using OR. e.g. Participant is in Study A or B. To ask the question "How many participants are in Study A and are also in Study B?", simply add the ancillary study criteria twice, once for study A and once for study B.
How do I combine criteria using "Either/Or" logic instead of "AND"s?
