What is the role of the Comparison step in formulating a clinical question?

• A. To Identify an Alternative Intervention or Standard of Care for Comparison
• B. To Determine the Research Design
• C. To Specify the Setting
• D. To Measure Outcomes

Answer: (A)

The Comparison step defines what you will compare the proposed intervention against. It provides the benchmark that lets you judge whether the new approach offers any benefit or safety advantage over what is currently used.

In practice, the comparator can be a placebo, the current standard of care, another treatment, or even no treatment. This choice anchors your question in real decision-making, so the resulting evidence will tell you about relative effectiveness or safety between the intervention and the alternative.

For example, in a pediatric context, you might ask whether a new analgesic regimen reduces pain more effectively than the standard regimen, or whether adding a nonsteroidal anti-inflammatory drug to the usual care provides additional benefit. The comparison is essential for interpreting outcomes and guiding clinical choices.

The other aspects—determining the study design, specifying the setting, or measuring outcomes—are addressed in their respective components of the question or study, not by the role of the comparison itself.
