What is one of the characteristics that must be specified in an estimand?

The control treatment
The population to be studied
The statistical software used
The study funding sources

The correct answer is: The population to be studied

One of the essential characteristics that must be specified in an estimand is the population to be studied. The estimand framework aims to clearly define the treatment effect of interest in a clinical trial or observational study. Specifying the target population is crucial because it outlines who the findings will apply to, ensuring that the analysis reflects the intended group of subjects. This facilitates the interpretation of results and their generalizability, as different populations may respond differently to treatments. In contrast, while the control treatment, statistical software, and study funding sources are important elements in the overall research design and methodology, they are not intrinsic characteristics of the estimand itself. The estimand’s focus is solely on characterizing the treatment effect, which inherently requires a clear definition of the population that will be affected by the treatment being studied.
