Professional Meta-Analysis Services for Evidence-Based Research
Are you conducting a systematic review and need reliable Meta-Analysis Services? I specialise in combining data from multiple studies to derive meaningful conclusions for research, clinical guidelines, or policy decisions. With over 7 years of experience in biostatistics and evidence synthesis, I deliver precise and actionable insights to enhance the quality of your research.
Please Contact Me before placing an order, as the listed prices are for reference purposes and may vary depending on the complexity of your study.
What I Offer:
Data Extraction and Preparation
- Extracting data from multiple studies, including effect sizes, sample sizes, and confidence intervals.
- Cleaning and organising data for accurate meta-analysis.
Meta-Analysis Methods
- Fixed-effect and random-effects models to assess study variability.
- Calculation of effect sizes (odds ratios, risk ratios, mean differences, etc.).
- Subgroup analysis and meta-regression to explore heterogeneity.
- Sensitivity analysis to test the robustness of results.
Visualisation and Reporting
- Forest plots to summarise effect sizes across studies.
- Funnel plots to assess publication bias.
- Comprehensive, publication-ready reports formatted to journal guidelines.
Expertise Areas
- Clinical Research: Synthesising data on drug efficacy, treatment comparisons, and diagnostic accuracy.
- Public Health: Evaluating community interventions, health policies, and vaccination studies.
- Education Research: Combining data on intervention effectiveness in educational programs.
- Psychology Research: Aggregating findings on behavioural and mental health studies.
- Epidemiology: Pooling data on risk factors and disease outcomes.
Statistical Tools I Use
- R: For advanced meta-analysis methods, forest plots, and subgroup analysis.
- Stata: For fixed-effects and random-effects modelling.
- Comprehensive Meta-Analysis (CMA): For effect size calculations and bias assessments.
- SPSS: For quick calculations and basic visualisations.
- Excel: For data organisation and basic summaries.
Fequently asked questions
1. What is Meta-Analysis?
Meta-analysis combines data from multiple studies to provide a comprehensive understanding of a research question. It helps synthesise evidence and draw more robust conclusions.
2. What types of studies can you include in a meta-analysis?
I work with clinical trials, observational studies, diagnostic studies, and intervention-based research across various disciplines.
3. Can you assess publication bias?
Yes, I provide funnel plots and statistical tests (e.g., Egger’s test) to evaluate publication bias in your meta-analysis.
4. What do I need to provide for meta-analysis?
You’ll need to provide extracted data (e.g., effect sizes, sample sizes, confidence intervals) or the studies to extract the data from. If you’re unsure, I can guide you.
5. Do you handle heterogeneity in studies?
Yes, I assess heterogeneity using statistical measures like I² and provide subgroup analyses or meta-regression to explore variability.
6. How do you ensure the accuracy of the analysis?
I use rigorous quality control measures, including double-checking data, verifying statistical methods, and validating results.
7. Can you handle large-scale meta-analyses?
Yes, I can handle meta-analyses with a large number of studies and complex data structures.
8. What if I need additional analyses after delivery?
Each package includes a set number of revisions. Additional analyses can be accommodated for a reasonable fee.
9. Do you provide publication-ready reports?
Yes, I deliver professional reports formatted to meet the requirements of high-impact journals.
10. Can you assist with systematic reviews?
Yes, I can assist with the data extraction, quality assessment, and synthesis phases of systematic reviews.
11. How do you handle data privacy?
Your data is treated securely, and I comply with all privacy regulations (e.g., GDPR). NDAs can be signed upon request.

Eric's support was pivotal in completing our meta-analysis for a healthcare research project. He demonstrated exceptional skill in handling heterogeneity, calculating pooled effect sizes, and performing subgroup analyses. Eric provided detailed explanations of the findings, ensuring our research met publication standards. His proactive communication and commitment to excellence made the entire process seamless. I would gladly work with him again for future projects.
