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.
