The Full Analysis Set (FAS) method in clinical trials is designed to include all randomized subjects after minimal elimination. This approach ensures that the analysis reflects as accurately as possible the intent-to-treat principle, which is fundamental in maintaining the integrity of clinical trial data.

By including nearly all randomized participants, the Full Analysis Set helps to mitigate the effects of bias, providing a more realistic view of how the treatment performs in a broader population. It allows researchers to evaluate the efficacy and safety of the intervention as it would occur in a typical clinical setting, rather than focusing only on those who adhered strictly to the study protocol or completed the trial.

Using this method can provide valuable insights into real-world applications of the therapy being studied, thus contributing to more robust findings about the treatment’s overall effectiveness and safety. In contrast, the other options focus on more restricted populations, which could lead to skewed results and limit generalizability.
