The Fragility Index of Hip Arthroscopy Randomized Control Trials: A Systematic Survey.

Arthroscopy: The Journal of Arthroscopy And Related, 2021
PURPOSE to characterize the fragility index (FI) of statistically significant results from randomized control trials (RCT) in hip arthroscopy. METHODS PubMed/MEDLINE, Embase, and Cochrane were queried for hip arthroscopy RCTs published between January ...

Platelet-Rich Plasma Versus Alternative Injections for Osteoarthritis of the Knee: A Systematic Review and Statistical Fragility Index–Based Meta-analysis of Randomized Controlled Trials

American Journal of Sports Medicine
Background: Based in part on the results of randomized controlled trials (RCTs) that suggest a beneficial effect over alternative treatment options, the use of platelet-rich plasma (PRP) for the management of knee osteoarthritis (OA) is widespread and ...

Evaluating the literature on preoperative androgen stimulation for hypospadias repair using the fragility index - can we trust observational studies?

Journal of Pediatric Urology, 2021
BACKGROUND Preoperative androgen stimulation (PAS) is typically used in hypospadias repair for patients with a proximal meatus or small glans size. Hypospadias PAS literature suffer from small sample sizes and lack of power to claim robust conclusions ...

When the p Value Doesn’t Cut It: The Fragility Index Applied to Randomized Controlled Trials in Colorectal Surgery

Diseases of the Colon & Rectum, 2021
BACKGROUND: The American Statistical Association, among others, has called for the use of statistical methods beyond p ≤ 0.05. The fragility index is a statistical metric defined as the minimum number of patients for whom if an event rather than a ...

Reassessing Fragility: A Comparative Analysis of the Fragility Index With the Relative Risk Index

2023
Abstract Background In biostatistics, assessing the fragility of research findings is crucial for understanding their clinical significance. This study focuses on the fragility index, unit fragility index, and relative risk index as measures to evaluate statistical fragility.

The Fragility Index

Clinical Spine Surgery
With the vast increase in spinal surgery research and accessibility, critical evaluation of studies is paramount. Historically, P values and confidence intervals have been the gold standard, but more recently, the inclusion of the Fragility Index has brought a more holistic approach. The Fragility Index aims to communicate the robustness of a trial and

A Hierarchical Fragile Watermarking with VQ Index Recovery

Journal of Multimedia, 2011
This paper proposes a hierarchical fragile watermarking scheme for image authentication with localization and recovery. Two phases are exploited for pixel-wise and block-wise authenticity. By applying the singular value decomposition (SVD), only a few pixels need to be modified to carry these watermark bits so we can produce high quality of the ...

The Fragility Index in Randomized Clinical Trials as a Means of Optimizing Patient Care

JAMA Surgery, 2018
Importance 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 ...
