How is the meta-analysis service priced?

Pricing depends on your chosen tier and project scope. The bundle with systematic review is available at a discounted rate. All tiers include unlimited revisions.

How many studies do I need for a meta-analysis?

A meta-analysis requires a minimum of two studies reporting comparable outcomes. Pooling is most informative with five or more studies.

What software do you use for meta-analysis?

We use R (metafor and meta packages) and Stata (metan suite). All code is fully annotated and reproducible.

Can you do a meta-analysis without a systematic review?

Yes. If you have already identified your studies, we can perform a standalone meta-analysis on your existing dataset.

What Our Meta-Analysis Service Delivers

A meta-analysis is a statistical method that combines the quantitative results of multiple independent studies to produce a single pooled estimate of effect. It is the gold standard of quantitative evidence synthesis, providing greater statistical power and more precise effect estimates than any individual study alone.

At Research Gold, our meta-analysis service provides researchers with expert biostatistical support for every stage of quantitative synthesis. Our team, led by PhD biostatisticians, implements all analyses using R (metafor and meta packages) or Stata, and delivers fully reproducible code alongside publication-ready figures and tables.

Whether you need a standalone meta-analysis for an existing dataset or a combined systematic review and meta-analysis, we deliver results that satisfy the most demanding peer reviewers and editorial boards.

What Is Included in Every Meta-Analysis

Effect Size Calculation and Standardization

We calculate or convert effect sizes from the data reported in primary studies. Depending on your outcome type, we compute:

Odds ratios and risk ratios for dichotomous outcomes
Mean differences and (Cohen's d, Hedges' g) for continuous outcomes

Our Meta-Analysis Process

Consultation. We discuss your review question, included studies, and outcomes of interest. If studies are already identified, we assess whether quantitative pooling is feasible.
Data preparation. We extract or verify the numerical data needed for meta-analysis from each included study. Where data are missing or incomplete, we apply validated imputation methods.
Statistical analysis. We run all planned analyses: pooled effect sizes (random-effects and/or fixed-effect models), forest plots, heterogeneity assessment, subgroup analyses, sensitivity analyses, meta-regression (where applicable), and publication bias tests.
GRADE assessment. For each critical and important outcome, we assess the certainty of evidence using the GRADE framework and produce summary of findings tables.
Deliverables. We deliver annotated R or Stata code, forest plots, funnel plots, summary tables, GRADE tables, and a complete results section for your manuscript.
Revisions. All tiers include unlimited revisions. If reviewers request additional analyses after submission, we handle those at no additional cost.
