Which topic outlines how variables are chosen and how data are collected?

• A. Set of Subjects to be Evaluated and Presentation of Data
• B. Integrated Summary
• C. Evaluation of Safety and Tolerability
• D. Choice of Variables and Data Collection

Answer: (D)

Planning which variables to measure and how data will be collected is central to the study design and data management. This topic covers defining endpoints (the variables to be measured) and detailing the data collection methods, sources, timing, and procedures to ensure consistent, high-quality data across all subjects. That combination—what to measure and how to collect it—is precisely what defines the data collection plan within a clinical trial. The other areas focus on different aspects: who is enrolled and how results are presented, the overall summaries of safety and efficacy, or separate safety/tolerability evaluations, none of which specify the data collection plan or variable definitions.
