I will do multivariate analyses for your clinical research project

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.

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.

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.

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.

This tier covers standard methods used in Medical Statistics: OR with Logistic regression, RR with Poisson and Negative Binomial models, and SURVIVAL with Cox model. Model fit is assessed with R-squared/pseudo-R-squared as appropriate. Ideal for simple projects and dissertations.

Upgrades Basic to assess EFFECT MODIFICATION (interaction) and adds Weighted analyses (including complex surveys like NHANES and BRFSS). It also adds an assessment for possible OUTLIERS (influence and leverage). Ideal for most medical thesis projects and journal submissions.

This is where high-complexity data comes in. This tier adds Repeated Measures for LONGITUDINAL studies (LMM/GLMM) or hierarchical data for MULTI-SITE studies and CROSS-OVER designs.

The ESSENTIAL tier will check model validity with tests for normality/proportional hazards assumptions, and check collinearity to remove offending variables. FOUNDATION adds diagnostic plots to "see" the issues with the data and model fit. PREMIUM adds state-of-the-art checks (case-by-case basis).

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.

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.
