Data is often collected using terms like “prior” and “ongoing” when start and end dates are not known. Those terms are not sufficient alone. One needs to know what time “prior” or “ongoing” refers to. (Prior to what time? Ongoing as of what time?) The SDTM variables –STRF and –ENRF were the first approach to dealing with converting “prior” or “ongoing” in collected data into terms that are clear in tabulations. These variables describe the start and end of an event or intervention relative to the study reference period in the DM domain. However, this approach can’t always be used, so new pairs of variables were introduced that can describe start or end relative to any point in time (--STRTPT and --STTPT, --ENRTPT and --ENTPT).
This webinar will help attendees understand the difference between the two sets of relative timing variables in SDTM and which to choose based on how data were collected.
