Seroconversion to multiple islet autoantibodies and risk of progression to diabetes in children

Results. Progression to type 1 diabetes at 10-year follow-up after islet autoantibody seroconversion in 585 children with multiple islet autoantibodies was 69.7% (95% CI, 65.1%-74.3%), and in 474 children with a single islet autoantibody was 14.5%.

Before you submit, Rich Review reads your thesis the way an examiner would. Before your defence, you practise with the questions your examiners are likely to ask.

Before you submit
Rich Review: an examiner-style report on the whole thesis
Tell it what your thesis should achieve. Rich Review measures every chapter against that goal and shows you what holds, what is weak and what is still missing.
- Optionally measured against the criteria of your grading rubric
- Gaps in the argument and places where it loses its thread
- The rules in your university's guidelines, and inclusive language if you want it
In the Pro and Lab packs, from USD 36 one-time. 30 to 125 credits per review, depending on length.
Rich Review, master's thesis
I want to show how early nutrition affects the risk of type 1 diabetes through the gut microbiome.
Good material, but no argument yet.
- MissingCh. 2
  There is no section on your method.
  You do not say how you searched for and selected the studies.
- MissingCh. 1
  There is no research question.
  Your introduction promises a summary. A master's thesis answers a question.
- WeaknessCh. 3
  Diet and microbiome sit side by side, unconnected.
  No chapter shows how one shapes the other.
Strength
Chapter 3 cleanly separates correlation from cause.
Example based on an invented master's thesis
Before your defence
Defence questions on your thesis
Your thesis turns into the questions examiners are likely to ask, with links to your chapters and answer outlines.
- 5 to 25 questions, from basic to committee level
- Filter by methodology, evidence, scope, contribution and follow-up
- More questions without repeats, export as a Word file
In the Pro and Lab packs. 15 credits per question set.
MethodologyCommitteeon ch. 3
Your evidence is mostly observational. How do you rule out that the microbiome only changes after autoimmunity has begun?
Answer outline
Cohorts such as TEDDY sample the microbiome from three months of age, before seroconversion.
That narrows down reverse causation but does not rule it out.
Chapter 3 names this as a limitation of the thesis.

What to know before uploading

What's the difference between Quick Check and source verification?

Quick Check checks whether your sources exist and their details are correct. It is free and needs no account. Source verification goes further: it reads your source PDFs to check whether they say what you cite.

Is this a plagiarism check?

No. Plagiarism software finds copied text. Acurio finds claims your source does not support and sources that do not exist. The two complement each other.

What happens to my thesis?

Acurio is a Swiss company hosted in the EU (Germany). Uploads use HTTPS, your documents are not used for training, and you can delete everything with a click.

Will my university see what I check?

No. Your university sees neither your thesis nor your results, not even if it uses Acurio itself.

Is Acurio a subscription?

No. Buy credits once (USD 24-60) and use them whenever you want. There is nothing to cancel.

Do I need Zotero?

No. Acurio reads Word, PDF and LaTeX. A Zotero export (BibTeX or RIS) improves matching but is optional.

Does Acurio replace my own review?

No. Acurio shows the finding, explanation and original passage. You decide when results are uncertain. Responsibility for your thesis stays with you.
