WebJan 1, 2024 · The Fragility Index (FI) is the minimum number of participants in a randomized clinical trial (RCT) whose status would have to change from a nonevent (not experiencing the primary end point) to an event (experiencing the primary end point) required to turn a statistically significant result to a nonsignificant result. WebFor these reasons, robust clinical evidence is critical. We aim to investigate the fragility index, fragility quotient, and risk of bias of clinical trial endpoints in HIV medicine. The fragility index represents the minimum amount of trial endpoint "nonevents" changed to "events" in one trial arm required to nullify statistical significance. WebThe fragility index (FI) is a powerful tool that can be used to assess the statistical strength of a study outcome.
