## Fragility Index Calculator Description
This tool helps clinicians and researchers assess the statistical robustness of trial results using the Fragility Index, based on the method by Walsh et al. (J Clin Epidemiol, 2014). By simulating event shifts and recalculating p-values via Fisher's Exact Test, it identifies how sensitive a study's significance is to small data changes.
