Description

For sample adults aged 40 years and older who ever had a CT colonoscopy or virtual colonoscopy (CTCOLEV) and who chose to respond in time period format, CTCOLLTP reports the time period (in days, weeks, months, or years) corresponding to the units since the respondent had their CT colonoscopy or virtual colonoscopy. CTCOLLNO reports the number of such time units (how many days, weeks, months or years).

 

The survey form directed interviewers to, "Enter time period for time since most recent CT colonography or virtual colonoscopy."

For more information, please see COLEV.
