Description
For sample adults aged 40 years and older who had ever had a CT colonography or virtual colonoscopy (CTCOLEV), CTCOLLDMO reports the calendar month of the respondent's most recent CT colonography or virtual colonoscopy. CTCOLLDMO should be used alongside CTCOLLDYR, which reports the calendar year of most recent CT colonography or virtual colonoscopy.
For more information about CT colonography or virtual colonoscopy variables, please see CTCOLEV.
