Description

For sample adults aged 40 years and older who ever had a CT colonography or virtual colonoscopy, CTCOLLGYRR2 is a recoded variable that reports the time since the respondent's most recent procedure using the same method as the 2000 survey.

The 2010 and 2015 Cancer Layout file notes that, "This is a time category recode for the time since the most recent CT colonography or virtual colonoscopy. All available information was used and the recoded variable was pre-filled with the response to the time category question first, if available. These data are provided by the respondent and are not imputed."

For more information, please see CTCOLEV (ever had CT colonoscopy).
