Medical treatments go through rigorous testing before approval because doctors, patients, and all relevant parties want to know they can rely on those treatments.
Indeed, there are occasional side effects and reasons why someone isn't the right fit for the treatment, but medical professionals must know the exceptions before approving treatments for broader use. So how do they ensure that their clinical trials effectively give them the information they need to rely on the treatments down the road?
One of the significant ways to ensure they collect sound data is through diverse applicants in their clinical research studies. Having applicants from all walks of life helps increase confidence in the treatment's effectiveness across all people. If there are disparities in clinical results, such as different outcomes for one gender versus another, doctors and patients must have that information before opting into the final version of the treatment. Diverse trials can help researchers adjust the formulation and timing of a treatment to create a final protocol that works as well as possible for many people.
