Currently, all trials, including those in rare diseases, that do not demonstrate a statistically significant benefit (i.e., P < 0.05) on the primary endpoint are classified as “negative”. This classification does not take into account a myriad of factors, including whether the trial was sufficiently powered, or had other statistically significant endpoints, or was terminated before completion, or was even initiated. This paper proposes reclassification of these trials into 5 categories: true negative, underpowered, inadequate, terminated or uninitiated, and valid. These categories reflect the trial characteristics more accurately and will be more useful to all stakeholders, especially the patients who participated in the trial and their healthcare providers.
