AutoBusinessForumTechnologyThe Fragility Index (FI) is a statistical measure used in the Analysis category to quantify the robustness of clinical trial results. It represents the minimum number of patients whose status would need to change from a non-event to an event to turn a statistically significant result into a non-significant one. This index is particularly useful in assessing the reliability of trial outcomes, offering a tangible metric to gauge the strength of the conclusions drawn.
In practical terms, a low Fragility Index suggests that the trial's findings are highly sensitive to minor changes in patient outcomes, indicating potential fragility in the results. Conversely, a high FI implies greater robustness, where conclusions are less likely to be overturned by small variations. This tool has become increasingly important in evidence-based medicine, helping researchers and clinicians critically evaluate the stability and reliability of clinical trial data.
