- Observations about concomitant medications used by the subject with the timing of use are collected in relation to the study reference period:
- For A, the start and end dates for the concomitant medication are known and are collected.
- Collection fields CMSTDAT and CMENDAT are used to collect the start and end dates for the concomitant medication.
- For D, the start date for the concomitant medication is unknown and cannot be collected.
- Collection field CMPRIOR is used to collect that the known start of the concomitant medication relative to exposure is prior to the subject's first exposure.
- Collection field CMENDAT is used to collect the known end date.
- For E, the subject has not discontinued the concomitant medication and therefore the end date for the concomitant medication cannot be collected.
- Collection field CMSTDAT is used to collect the known start date.
- Collection field CMONGO is used to collect that the use of the concomitant medication is ongoing relative the subject's last exposure.
- The following variables are used to represent collected data in subsequent tabulation datasets:
- RFSTDTC and RFENDDTC represent the dates of the subject's first and last exposure respectively in the Demography (DM) dataset.
- CMSTRF and CMENRF represent values from collection variables CMPRIOR and CMONGO in the Concomitant Medications (CM) dataset.

The reference time points (represented by B and C) are part of the overall context of the study. - Observations about concomitant medications used by the subject with the timing of use are collected in relation to the reference time points:
- For A, the start and end dates for the concomitant medication are known and are collected.
- Collection fields CMSTDAT and CMENDAT are used to collect the start and end dates for the concomitant medication.
- For D, the start date for the concomitant medication is unknown and cannot be collected.
- Collection field CMPRIOR is used to collect that the known start of the concomitant medication relative to Screening is prior to the subject's screening visit.
- Collection field CMENDAT is used to collect the known end date.
- For E, the discontinuation date for the concomitant medication is unknown and cannot be collected.
- Collection field CMSTDAT is used to collect the known start date.
- Collection field CMONGO is used to collect that the use of the concomitant medication is ongoing relative the subject's date of last contact.
- The following variables are used to represent collected data in subsequent tabulation datasets:
- CMSTTPT and CMENTPT represent the date or a short description of the subject's screening visit and last contact respectively in the CM dataset.
- CMSTRTPT and CMENRTPT represent values from collection variables CMPRIOR and CMONGO in the CM dataset.
