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.
