SDTMIG Section 4.4.7, Relative Timing Variables needs to be linked to a Section in this TIG. This section seems to be missing.
This is an example of an SDTM dataset used to represent the medical history collected on the above CRF. This CRF was designed to allow the sponsor to use either MHENRF or MHENRTPT to represent an event that was ongoing. This SDTM dataset used MHENRTPT. More information can be found in SDTMIG Section 4.4.7, Relative Timing Variables.
Rows 1-2:
The reported events were coded using a standard dictionary. MHDECOD and MHBODSYS display the preferred term and body system assigned through the coding process. MHENRTPT was populated based on the response to the "Ongoing" question on the General Medical History CRF. MHENTPT displays the reference date for MHENRTPT, that is, the date the information was collected. If "Yes" was specified for Ongoing, MHENRTPT = "ONGOING"; if "No" was checked, MHENRTPT = "BEFORE".
Row 3:
The start and end date of the reported event was displayed.
