Where Should You Get Your Medical Thesis Analysed?

If you are running a residency thesis, a clinical study or a retrospective chart review, you have four realistic sources of statistical support: your faculty's biostatistics department, a senior resident or attending with a statistics background, an individual freelance statistician, or an analysis service such as GetBayes. In medicine the deciding capabilities are specific: survival analysis (Kaplan-Meier, log-rank, Cox), diagnostic test evaluation (ROC, AUC, cut-off selection), sound variable selection in multivariable logistic regression, and reporting that follows STROBE or CONSORT. Ask about these by name before you commit.

There is also a timing question, and in medicine it is the expensive one: you need a statistician at the protocol and ethics-approval stage, not after the data is collected. Below you will find the channels compared, the questions worth asking, the warning signs worth walking away from, and price ranges compiled from public listings. GetBayes is one of these options and a paid service — we state plainly what we do at the end of the page.

Who is this guide for?

  • Residents writing a specialty thesis, and their supervisors

  • Physicians planning a retrospective chart review, case-control or cohort study

  • Anyone who needs a sample size justification for an ethics committee application

  • Health sciences researchers whose manuscript returned with statistical revisions

  • Teams running a randomised controlled trial that must be reported to CONSORT

The expensive mistake: asking at the wrong time

Medical research needs statistical input at two points, and most people only ask at the second one. The first is the protocol and ethics stage: how many patients you need (a priori power analysis), what your primary endpoint will be, and in what format the data should be collected. The second is the analysis stage, once the data is in.

The problem is that skipping the first stage limits what the second can do. In an underpowered study, "no significant difference was found" may reflect insufficient power rather than an absence of effect — and that can only be reported honestly, not repaired afterwards. Variables missing from a chart review cannot be collected retroactively either. Half an hour before data collection is cheaper than weeks at the end of the thesis.

Where you can get the analysis done

Each of these works in some situations; which fits you depends on your study type and your calendar.

Eight questions to ask before you commit

These are specific to medical research, and how clearly they are answered predicts the comments you will get from reviewers:

  • How will you analyse time-to-event data? You want to hear Kaplan-Meier curves, the log-rank test and Cox regression for risk factors; summarising follow-up data with a simple chi-square discards information.

  • How will you choose the cut-off in my diagnostic test study? ROC curve, AUC and the Youden index for the sensitivity-specificity trade-off — plus an awareness that PPV and NPV depend on prevalence.

  • Which variables go into the multivariable model? The answer should combine clinical rationale with a univariable screening criterion; "we put everything in" invites overfitting, so the events-per-variable rule is worth asking about.

  • How will missing data be handled? Missingness is the rule in chart reviews; "we drop incomplete rows" is not a complete answer on its own — how much is missing and how it will be reported both matter.

  • Which reporting guideline will you follow? STROBE for observational studies, CONSORT for trials, STARD for diagnostic accuracy — editors notice this immediately.

  • Can you write the sample size justification for the ethics committee? They expect a paragraph explaining the assumed effect size and power, not just a number.

  • Will the tables match my target journal's format? Medical journal conventions (n (%), mean ± SD or median [IQR], a p-value column) differ from thesis formatting.

  • What happens if a reviewer asks for more analyses? The scope and cost of revisions should be agreed in writing; additional requests during peer review are entirely normal.

Red flags

These are not negotiating points — they are signals about the validity of your study:

  • Any hint of "we'll make the p-value significant." Significance cannot be promised; promising it means tests will be repeated or group boundaries shifted until something appears. Even if a committee misses it, peer review often will not.

  • A proposal to run dozens of subgroup analyses and report only the significant ones. Multiple comparisons without correction manufacture false positives.

  • Being asked for identifiable patient data. Names, national ID or file numbers are not needed for analysis; de-identify before sending.

  • Raw SPSS output with the interpretation left to you. What you defend in a thesis is the interpretation, not the output.

  • A price quoted without asking about the study design. A chart review and a randomised trial are not the same effort.

  • An offer to "write the thesis too." Analysis support has a clear boundary; beyond it lies an academic integrity problem.

What to send in your first message

Whoever you contact, sending these in one message gets you a realistic quote and a realistic timeline:

  1. 01

    Study type and question

    Retrospective or prospective, case-control or cohort; your primary endpoint and the groups being compared.

  2. 02

    De-identified data

    Your Excel or SPSS file with names, IDs and file numbers removed. Missing values and messy coding are fine.

  3. 03

    Ethics approval and timeline

    The scope of your ethics approval and your submission or defence date; if you are still at protocol stage, say so and we start with sample size.

  4. 04

    Target format

    Your thesis formatting guide or the journal you plan to submit to — tables are built accordingly.

The ethical line, and where we stand

Statistical support is routine in medicine — in many clinical studies a biostatistician is part of the team from the start. The line is clear: the data must be real and yours, and you must understand and be able to defend the methods. A good report therefore states not only the result but the justification for every methodological choice.

GetBayes is one of the options above: we analyse medical research from retrospective reviews to randomised trials, from survival analysis to diagnostic test evaluation, and report it in the table layout medical journals expect, with effect sizes and confidence intervals. The analysis itself usually takes 15 minutes; delivery is same-day, often within hours or even minutes. Revisions driven by an advisor, committee or reviewer are free, and we keep answering questions after delivery. If you are at the ethics application stage, we prepare the sample size calculation together with its justification text.

Frequently asked questions

Can I have my residency thesis statistics done externally?

Yes — analysis support is a common and accepted practice in medical research; just check your institution's thesis regulations. What matters is that you understand the methods and can defend them, which is why every method choice is justified in the report and we stay available for questions after delivery.

Is it safe to share patient data?

Share de-identified data: analysis does not need names, national IDs or file numbers — age, sex and clinical variables are enough. At GetBayes your data is used only for your study, never shared with third parties, and automatically deleted no later than 90 days after final delivery; you can request earlier deletion at any time.

Do you calculate sample size for my ethics application?

Yes. We compute the required sample size from the expected effect size, alpha and power, with sensitivity graphs, and write the justification paragraph the committee expects. Doing this before data collection is what prevents an underpowered study at the end.

My data is messy — do I need to clean it first?

No. Messy and incomplete data is the norm in chart reviews, and we don't send it back with "fix this and come again." We pinpoint exactly what is wrong, fix what can be fixed on our side, clean the dataset and document in the report how each issue was handled. We only come back to you for decisions that are genuinely yours, such as an exclusion criterion.

My manuscript came back with statistical revisions — can you run the extra analyses?

Yes, this is one of the most common requests we get. We run the analyses the reviewer asked for, update the methods section where needed, and draft the statistical response letter. Reviewer-driven revisions are free at GetBayes.

How fast is delivery?

The analysis itself usually takes 15 minutes and delivery is same-day, often within hours or even minutes. Total elapsed time is generally driven by gaps in the data and requests for additional analyses; you can reach us at every stage of the process. Urgency never changes the price.
