This is an example CRF used to collect Disposition Events. In this study, subjects were randomized to a trial, which contain three epochs. A screening epoch, a product exposure epoch,, where subjects were required to use the tobacco product as described in the protocol, and a follow-up epoch.. The Disposition Event CRF was collected at the end of each epoch of the trial. The sponsor may select the the Completion/Reason for Non-Completion terms from Controlled Terminology.

This is an example of an SDTM dataset used to represent the data collected on the above example CRFs.
Rows 1, 2, 6, 8, 9, 12, 13, 17, 18:
Show records for protocol milestones. DSTERM and DSDECOD are populated with the same value, the name of the milestone. Note that for randomization events, EPOCH = "SCREENING", because randomization occurred before the start of product exposure, during the screening epoch.
Rows 3-5:
Show 3 records for a subject who completed 3 stages of the study ("SCREENING", "PRODUCT EXPOSURE", "FOLLOW-UP").
Row 7:
Shows disposition of a subject who was a screen failure. The Disposition CRF showed that the subject discontinued for a " PROTOCOL DEVIATION ". The specify reason the subject was a screen failure was then collected using DSTERM. Because the subject did not complete the screening epoch, DSDECOD is not “COMPLETED” but another appropriate controlled term, "PROTOCOL DEVIATION ". The date of discontinuation is in DSSTDTC. The protocol deviation event itself would be represented in the DV dataset.
Rows 10-11:
Show disposition of a subject who completed the screening stage but did not complete the protocol exposure epoch. For completed epochs, both DSTERM and DSDECOD are "COMPLETED". For epochs that were not completed, the verbatim reason for non-completion of the product exposure epoch is in DSTERM, while the value from controlled terminology is in DSDECOD.
Rows 14-16:
Show disposition of a subject who completed prouduct exposure epoch, but did not complete follow-up. Note that for final disposition event, the date of collection of the event information, DSDTC, was different from the date of the disposition event (the subject's death), DSSTDTC.
Rows 19-21:
Show disposition of a subject who discontinued the product exposure epoch due to an adverse event, but who went on to complete the follow-up epoch of the trial.
