Description
For sample adults aged 40 years and older who ever had a CT colonography or virtual colonoscopy (CTCOLEV) and who chose to respond in time period format, CTCOLLNO reports the number of time units (how many days, weeks, months, or years) since the respondent had their most recent CT colonography or virtual colonoscopy. CTCOLLNO should be used alongside CTCOLLTP, which reports the corresponding type of time period (in days, weeks, months, or years).
For more information about CT colonography or virtual colonoscopy variables, please see CTCOLEV.
