1What does the acronym CDISC stand for in clinical trials data standards?
A.Clinical Data Interchange Standards Consortium
B.Centralized Drug Information Standards Committee
C.Clinical Database Integration Standards Council
D.Computerized Data Inspection and Submission Coalition
Explanation: CDISC stands for Clinical Data Interchange Standards Consortium, a global non-profit organization that develops data standards (SDTM, ADaM, SEND, Define-XML) used in regulatory submissions to FDA, PMDA, and other agencies.
2Which CDISC standard defines the structure of submission datasets describing observed clinical trial data?
A.ADaM
B.SDTM
C.SEND
D.ODM
Explanation: SDTM (Study Data Tabulation Model) defines the standard structure for submission datasets that contain observed/collected clinical trial data, organized into domains such as DM, AE, CM, EX, LB, and VS.
3Which CDISC model is specifically designed to support statistical analysis of clinical trial results?
A.SDTM
B.SEND
C.ADaM
D.CDASH
Explanation: ADaM (Analysis Data Model) is built from SDTM datasets and is structured to support statistical analyses for FDA submissions. ADaM datasets are analysis-ready and traceable back to SDTM.
4What is the purpose of the USUBJID variable in SDTM and ADaM datasets?
A.It stores the subject's date of birth
B.It is a unique identifier for a subject across all studies in a submission
C.It identifies the visit number
D.It identifies the treatment arm
Explanation: USUBJID is the Unique Subject Identifier and must be unique across all studies within a submission. It is typically constructed by concatenating STUDYID, SITEID, and SUBJID to ensure global uniqueness.
5Which SDTM domain holds Demographics data for trial subjects?
A.DS
B.DM
C.MH
D.TS
Explanation: DM is the Demographics domain in SDTM and is a Special Purpose domain. It contains one record per subject with variables such as USUBJID, AGE, SEX, RACE, ETHNIC, ARM, and COUNTRY.
6Which SDTM domain captures Adverse Events?
A.AE
B.CE
C.MH
D.DS
Explanation: AE is the Adverse Events domain. Required variables include AETERM (reported term), AEDECOD (dictionary-derived term), AESEV (severity), AESER (serious flag), AESTDTC (start date), and AEENDTC (end date).
7In the SDTM AE domain, which variable identifies whether an adverse event was serious?
A.AESEV
B.AESER
C.AEREL
D.AEACN
Explanation: AESER is the Serious Event flag (Y/N) and indicates regulatory seriousness as defined by ICH E2A criteria (death, life-threatening, hospitalization, disability, congenital anomaly, or other medically important event).
8Which date format is required for ISO 8601 character date variables (--DTC) in SDTM?
A.MM/DD/YYYY
B.DDMONYYYY
C.YYYY-MM-DDThh:mm:ss
D.YYYYMMDD
Explanation: SDTM --DTC variables use ISO 8601 extended format YYYY-MM-DDThh:mm:ss. Partial dates are allowed, e.g., 2026-05 or 2026-05-09T14:30. The format is character, not numeric.
9What does the --SEQ variable represent in SDTM domains?
A.The sequence of dosing within a visit
B.A unique sequence number for each record within USUBJID and DOMAIN
C.The protocol version sequence
D.The order of laboratory tests collected
Explanation: --SEQ (e.g., AESEQ, CMSEQ, LBSEQ) provides a unique sequence number for each record within a subject (USUBJID) within a domain. It is required for traceability and to uniquely identify records.
10Which SDTM domain stores Concomitant Medications data?
A.EX
B.CM
C.EC
D.MH
Explanation: CM is the Concomitant Medications domain. It captures non-study medications taken by the subject. Key variables include CMTRT (reported name), CMDECOD (WHO-DD coded name), CMINDC (indication), CMSTDTC, and CMENDTC.

SAS Clinical Trials Programming Study Tips from Top Performers

1Treat the 20% Validation domain as the highest-leverage study area: master PROC COMPARE, &SYSINFO bitmap, Pinnacle 21, and double-programming workflows.
2Memorize SDTM key conventions: ISO 8601 in --DTC, study Day 1 = RFSTDTC (no Day 0), USUBJID uniqueness across studies, and --SEQ uniqueness within USUBJID/DOMAIN.
3Drill ADaM derivations until automatic: BASE selection via ABLFL='Y', CHG = AVAL - BASE, PCHG = 100*(CHG/BASE), TRTEMFL, ANL01FL, and ADTTE CNSR convention (0=event, 1=censored).
4Practice macro debugging with OPTIONS MPRINT MLOGIC SYMBOLGEN; build at least one parameterized clinical macro using keyword parameters and %LOCAL scoping.
5Code real TLFs end-to-end: AE incidence by SOC/PT/arm using ADSL denominator and ADAE numerator with COUNT(DISTINCT USUBJID), then render with PROC REPORT and ODS RTF.
6For statistics, focus on PROC LIFETEST + PROC PHREG for time-to-event, PROC MIXED MMRM for longitudinal data, and PROC GLM ANCOVA for change-from-baseline.
