Expert Biostatistics Consulting for Medical and Health Research
Biostatistics consulting provides researchers with expert statistical guidance and hands-on data analysis support. Whether you need help designing a study, calculating sample size, running complex analyses, or interpreting results for publication, a qualified biostatistician ensures your methods are rigorous, your analyses are correct, and your findings withstand peer review.
At Research Gold, our biostatistics consulting team is led by Prof. David Okonkwo (PhD, Biostatistics) and includes PhD-level statisticians with direct experience in clinical trials, observational studies, meta-analyses, and health services research. We use R, Stata, SPSS, and SAS depending on your project requirements, and deliver fully annotated, reproducible code with every engagement.
Statistical Services We Provide
Study Design Consulting
We help you choose the right study design and analytical approach before data collection begins. This includes randomized trial design, cohort and case-control study planning, cross-sectional survey design, and quasi-experimental methods.
Sample Size Calculation and Power Analysis
We calculate the minimum sample size needed to detect a clinically meaningful effect with adequate statistical power. We provide detailed justification for grant proposals and ethics applications, including effect size assumptions, alpha level, power (typically 80% or 90%), and expected dropout rates. Try our free power analysis calculator for initial estimates.
Data Analysis for Medical Research
Our data analysis for medical research covers the full spectrum of quantitative methods:
- Regression analysis: linear, logistic, ordinal, multinomial, Poisson, negative binomial
- Survival analysis: Kaplan-Meier curves, Cox proportional hazards, competing risks models
- Mixed-effects models: linear and generalized linear mixed models for clustered or repeated-measures data
- Propensity score methods: matching, inverse probability weighting, stratification
- Bayesian methods: Bayesian regression, hierarchical models
- Diagnostic test accuracy: sensitivity, specificity, ROC curves, likelihood ratios
- Time series and longitudinal analysis: growth curve models, generalized estimating equations
Meta-Analysis Statistics
If you have already conducted a systematic review and need the quantitative synthesis, we provide standalone meta-analysis support including effect size calculation, heterogeneity assessment, forest plots, funnel plots, and GRADE tables. See our meta-analysis service page for full details.
Explore our free statistical tools: effect size calculator, sample size calculator, chi-square calculator, and ICC calculator.
Statistical Interpretation Service
Already have your results but unsure what they mean? Our statistical interpretation service translates your statistical outputs into clear, publication-ready language. We explain effect sizes in clinical context, assess whether assumptions were met, and help you present results accurately in your methods and results sections.
Software We Use
| Software | Common Uses |
|---|---|
| R | Meta-analysis (metafor, meta), regression modeling, survival analysis, Bayesian methods, publication-quality figures |
| Stata | Clinical trial analysis, survey data, panel data, meta-analysis (metan), epidemiological methods |
| SPSS | Descriptive statistics, ANOVA, chi-square tests, logistic regression, common in social science research |
| SAS | Clinical trial reporting, FDA submissions, pharmaceutical research |
All code is fully annotated and reproducible. We choose the software that best fits your project or use the software specified by your institution or journal.
Our Process
-
Consultation. We discuss your research question, study design, data structure, and analytical goals.
-
Analysis plan. We draft a statistical analysis plan documenting all planned primary and secondary analyses, handling of missing data, and sensitivity analyses.
-
Data analysis. We clean your data, run all planned analyses, and produce tables and figures formatted for your target journal.
-
Results and code. We deliver annotated code, statistical outputs, formatted tables, figures, and a narrative summary of results ready for your manuscript.
-
Revisions. We handle reviewer requests for additional analyses at no additional cost within the engagement scope.
Who Uses Our Biostatistics Consulting
- Clinical researchers needing statistical analysis for journal submissions or regulatory reports
- PhD candidates requiring study design guidance and statistical analysis for their dissertation
- Grant applicants needing sample size justifications and statistical analysis plans for NIH, NIHR, or institutional proposals (see our grant methodology service)
- Medical residents and fellows analyzing data for their research projects
- Research teams that lack in-house biostatistical expertise
- Authors responding to reviewer requests for additional or corrected statistical analyses (see our response to reviewers service)
Testimonials
"I had survival data from a multicenter cohort study and needed Cox regression with competing risks analysis. Research Gold's biostatistician not only ran the analysis but explained every assumption and produced figures that my co-authors immediately understood. Published in JAMA Network Open."
