SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Detects and quantifies publication bias in meta-analyses by combining visual funnel plots with quantitative tests and adjustment methods, helping researchers assess robustness of conclusions.

Core Features & Use Cases

  • Funnel plot visualization to inspect symmetry and potential bias across studies.
  • Egger's regression test and Begg's test to statistically evaluate asymmetry.
  • Trim-and-fill adjustments and more advanced selection-model approaches to estimate the impact of missing studies.
  • Clear reporting of original and adjusted effect estimates to inform sensitivity analyses.
  • Suitable for integration into analysis pipelines in evidence synthesis across disciplines.

Quick Start

Provide a funnel-plot based bias assessment for a meta-analysis, including Egger's test results and optional trim-and-fill adjustments.

FAQPage Schema
How do I detect publication bias in a meta-analysis using R?

Funnel plot analysis visually inspects study symmetry to detect publication bias in meta-analyses. This Skill generates funnel plots using R and the metafor package, helping researchers identify potential missing studies across biomedical and social science datasets.

How do I run Egger's test and trim-and-fill adjustments for meta-analysis robustness?

Running Egger's test and trim-and-fill adjustments quantifies publication bias and estimates the impact of missing studies. This Skill calculates these statistical metrics using R, reporting original and adjusted effect estimates for sensitivity analyses.

Do I need the metafor package in R to perform funnel plot asymmetry tests?

Yes, you need the metafor package in R to perform funnel plot asymmetry tests. This Skill requires the metafor environment to execute Egger's regression test, Begg's test, and advanced selection-model approaches for bias evaluation.

What is the best way to assess the impact of missing studies in evidence synthesis?

Assessing the impact of missing studies in evidence synthesis is best achieved through selection-model approaches and trim-and-fill adjustments. This Skill applies these methods to estimate how missing data affects pooled effect estimates.

Can I use selection models to adjust pooled effects for publication bias in biomedical research?

You can use selection models to adjust pooled effects for publication bias in biomedical research. This Skill applies advanced selection-model approaches alongside standard adjustments to provide clear reporting of original and adjusted effect estimates.
