Traditionally, the gold standard has been the superiority trial , which aims to demonstrate that a new treatment is better than its comparator. However, as medicine has evolved—particularly in areas where effective treatments already exist— non‑inferiority trials have become increasingly impor...

The pressure to produce a significant p-value often triggers a "statistical selection crisis": a frantic search for any test that seems to "fit" the data. In medical research, "association" is not a one-size-fits-all term. It is a mathematical relationship defined by the architecture of your data. Choosing the wrong tool doesn't just lead to an incorrect p-value; it can fundamentally misrepresent the clinical reality you are trying to uncover...
