Retraction Fragility Quantifier — How robust is your meta-analysis to study retractions?

Methods

• Retraction Fragility Index (RFI) — minimum retractions to reverse conclusion
• Leave-one-out — impact of each study's removal
• Greedy sequential removal — most impactful first
• Combinatorial search — exhaustive for depths 1-3

Plots

• Impact waterfall (sorted by absolute effect change)
• Fragility curve (P-value vs retractions removed)
• Leave-one-out forest plot

Examples

• Statins & Mortality (robust, RFI > 5)
• Ivermectin & COVID (fragile, RFI = 1)
• Surgery vs Medical (marginal)
