Methodology from someone who reviews it

I work in evidence synthesis and review manuscripts for journals, so I know what editors and reviewers look for. My aim is a review you understand, can defend and can publish.

  • Methods aligned with JBI, Cochrane and PRISMA guidance
  • Experience across medicine, nursing, psychology and public health topics
  • Clear explanations, so you stay in control of your own work
  • Ethical, transparent support that respects your institution's academic integrity rules

Frequently asked questions

If your question isn't here, just ask in the form.

Which type of review do I need?

It depends on your question. A literature review explains a topic or builds an argument, a scoping review maps all the evidence on a topic, and a systematic review answers a focused question, often with a meta-analysis. The free assessment includes a recommendation.

Is the first assessment really free?

Yes. You receive confidential feedback within 48 hours, with no obligation to continue.

Do you write the review for me?

I provide methodological support, training and expert input so that the work remains yours and meets your institution's rules on academic integrity. The scope is agreed with you in advance.

Is my project kept confidential?

Yes. Your topic, data and drafts are never shared with anyone else.

How much does it cost?

It depends on the type of review and the stages you need help with. After the free assessment you receive a clear quote before any work begins.

Can you help in Greek?

Yes. Support is available in English and Greek.
