The Percent Fragility Index [PDF]
This article proposes the Percent Fragility Index (PFI) as an improved measure of statistical fragility in biomedical research. The PFI quantifies the percentage change in outcomes needed to change a study's statistical significance from positive to negative or vice-versa.

A critique of the fragility index
In The Lancet Oncology , Joseph Del Paggio and Ian Tannock report on a retrospective analysis of the fragility indices of phase 3 trials used by the US Food and Drug Administration (FDA) to approve anticancer drugs. 1 The authors conclude that “many phase 3 randomised controlled trials supporting FDA-approved anticancer drugs have a low fragility index,

Assessing and visualizing fragility of clinical results with binary outcomes in R using the fragility package [PDF]
With the growing concerns about research reproducibility and replicability, the assessment of scientific results’ fragility (or robustness) has been of increasing interest.

Fragility exposure index: Concepts, measurement, and application [PDF]
AbstractDefinitions of fragility are focused at the level of the state, but this should not be considered to suggest that individuals with heterogeneous endowments experience a state of fragility in the same way. Nor does it suggest that all subregions of a fragile country exist in this state.

Nonattainability of the Fragility Index. [PDF]
The fragility index (FI) is intended to quantify how many outcome changes would be required to convert a statistically significant two-arm trial result into a nonsignificant one. A reliable statistical metric should produce a result for every valid case it evaluates.

Beyond the Fragility Index. [PDF]
ABSTRACTThe results of randomized clinical trials (RCTs) are frequently assessed with the fragility index (FI). Although the information provided by FI may supplement the p value, this indicator presents intrinsic weaknesses and shortcomings. In this article, we establish an analysis of fragility within a broader framework so that it can reliably ...
