Codes and Frequencies
For female sample adults age 30 or older who ever had a breast MRI (BMRIEV), BMRILGYRR reports the duration since their last breast MRI in a consistent format of grouped years (from "a year ago or less" up to "over 5 years ago"). BMRILGYRR is a recode of data collected from respondents who used a variety of reporting formats to indicate the length of time since their last breast MRI.
Interviewers asked, "When did you have your most recent breast MRI?" Respondents could answer either in terms of calendar month and year (recorded in BMRILDMO and BMRILDYR) or in terms of a time period and number of units for that time period (recorded in BMRILTP and BMRILNO).
Respondents who failed to give a complete response in terms of either the month and year or in terms of the number and time period format were asked to estimate the number of years since their last breast MRI test (BMRILGYR).
These various responses on time since most recent breast MRI are recoded into a common grouped year format in BMRILGYRR.
