About this Gig
Vetted Pro
Need to know if your study results are more than just noise? Wondering if the difference between your groups is statistically significant?
Every breakthrough starts with a solid foundation. This service focuses on the fundamental building blocks of medical statistics: comparing groups, assessing correlations, and describing your study population with professional clarity.
What we'll build together:
- Publication-Ready Tables: Formatted to medical journal standards.
- Clear Interpretation: A report in plain language ready for your manuscript or thesis.
- The "Grand Finale": Every delivery includes a call to walk through the results. I want you 100% confident explaining these findings to your committee or peers.
Our tools for that:
- Student's t-test (paired / unpaired)
- Difference in proportions test (unpaired)
- Chi-square test of independence or Fisher's exact test (unpaired)
- McNemar test of proportions (paired)
- One-way ANOVA + posthoc tests
- Standardized effect size: Cohen's D and h
- Odds ratios (OR)
- Risk ratios (RR)
- Kaplan-Meier + log-rank tests
PS: I offer progressive discounts for bundling services so I can assist you with all phases (Study Design, e-CRF setup, and Final Analysis).

FAQ
Should I chat with you before placing an order?
I would be delighted to chat with you before taking your order! Whenever possible I like to present past work from my portfolio. I can then direct you to a stock package or I can provide a Custom Offer that fits your exact needs and budget.
What is the deliverable for this service?
All reports start describing the STUDY POPULATION, with Table 1 and Figure 1 ("Outcome"). The PRIMARY ANALYSIS includes Table 2 and Fig. 2 ("Effects"), with an "Age by Sex" Fig. in the Appendix. Per STROBE/CONSORT guidelines, Table 1 does not include p-values to avoid misleading interpretations.
What is the difference between the Simplified Report and the Full Report?
The SIMPLIFIED REPORT mimics a journal paper: significant results are highlighted and described, with technical information in parentheses (estimate, 95% CI and p-value). The FULL REPORT expands that with a deeper interpretation, connecting the dots between data and its clinical relevance.
Will you do the job in SPSS/Stata/SAS/Graphpad/etc?
Probably not, since I use R for all my work. By specializing in one tool I can focus on providing high-quality content, written clearly and understandably, with professional-looking tables and figures. The Final Report is delivered in DOCX/PDF with content ready to copy to your document.
I need you to use a particular set of methods
I will give you my methodological recommendations, based on professional and teaching experience in the field, while also observing international reporting guidelines (like STROBE and CONSORT). You can consider my advice and still feel free to reject it. I will deliver whatever we agree upon.
Are ANOVA and Survival Analysis within the scope of this service?
Tough question, it depends on complexity. I will do one-way ANOVA and Kaplan-Meier plots in my Univariate Analysis service. Two-way or Factorial ANOVA and Survival Analysis adjusting for confounders (age, sex, comorbidities) will require the Multivariate Analysis service.
Will you do p-value adjustments for multiple comparisons?
Doing solid research is hard, and a large enough study sample is even harder to acquire. Even though this is not usual practice in the biomedical research literature, I strongly recommend it. No extra fee will be charged for doing solid research, but the time for delivery might need adjustment.
