Question 1

While performing data validation checks, you are tasked with writing a SAS program that will identify all subjects who have a discrepancy in their record: the variable 'EndDate' is before the 'StartDate'. Which programming technique would be best suited to identify these subjects?

Options :

A : A DATA step with a WHERE statement to subset records where 'EndDate' < 'StartDate'.

B : A DATA step with an IF-THEN statement to flag records where 'EndDate' < 'StartDate'.

C : PROC COMPARE to compare 'StartDate' and 'EndDate' for each subject.

D : PROC FREQ to calculate frequencies of 'EndDate' and 'StartDate'.

Answer: B

Question 2

An SAS programmer intends to generate a listing report using SAS 9.4, which should be optimized for Word destination with specific settings to ensure that the output resembles traditional printed documents. This report includes multiple tables that should fit within standard margins when the Word document is printed. Which combination of output delivery system (ODS) statement attributes should the programmer use to meet these requirements?

Options :

A : ods word file='report.docx' startpage=no;

B : ods word file='report.docx' startpage=yes;

C : ods word file='report.docx' startpage=no cols=2;

D : ods word file='report.docx' startpage=yes cols=2;

Answer: A

Question 3

You are working on a clinical trial data set in SAS, and you need to create a new variable that captures the number of days since the start of the study. The study start date is available as an automatic variable called `Study_Start_Date`, and each patient's visit date is recorded in a variable called `Visit_Date`. Which of the following code snippets correctly calculates the new variable `Days_Since_Start`?

Options :

A : `Days_Since_Start = Visit_Date - Study_Start_Date;`

B : `Days_Since_Start = intck('day', Study_Start_Date, Visit_Date);`

C : `Days_Since_Start = retain(Study_Start_Date) - Visit_Date;`

D : `Days_Since_Start = dif(Visit_Date - Study_Start_Date);`

Answer: A

Question 4

Which key organization is responsible for oversight and approval of clinical trials in the United States, ensuring that they are conducted according to regulatory requirements to safeguard participant health and collect reliable data?

Options :

A : The National Institutes of Health (NIH)

B : The Food and Drug Administration (FDA)

C : The European Medicines Agency (EMA)

D : The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH)

Answer: B

Question 5

A clinical trial dataset is being prepared for statistical analysis and submission to a regulatory authority. Which of the following best describes the purpose of applying the CDISC Analysis Data Model (ADaM) standards to the dataset?

Options :

A : To define the dataset in a way that is specific to the individual clinical trial without consideration for cross-study comparisons.

B : To ensure that the dataset only includes variables that are directly derived from the Case Report Form (CRF).

C : To standardize the dataset structure and variables to facilitate efficient review by regulatory authorities and ensure consistency across studies.

D : To anonymize the clinical trial data to protect patient confidentiality before submission to regulatory agencies.
