Systematic review, meta-analysis, or scoping review?

Not sure which review your question calls for? Here is the quick distinction, and where to go next for each one.

Systematic review

An exhaustive, pre-registered answer to one focused question, screened in duplicate and reported to PRISMA 2020.

See how we run it

Meta-analysis

A quantitative synthesis that pools the included studies into one effect estimate, with heterogeneity, forest, and funnel plots.

Meta-analysis services

Scoping review

A broader map of what evidence already exists on a topic, reported to PRISMA-ScR, often before a full systematic review.

How we write your systematic review, step by step

A transparent, pre-registered process that follows the recognised steps of a systematic review. Nothing is decided after the results are in, which is exactly what reviewers and editors look for.

  1. 1

    Protocol and registration

    We define the question with PICO or PICOS, pre-specify eligibility and methods, and prepare a registration-ready PROSPERO record you submit before any screening begins.

  2. 2

    Search and de-duplication

    A reproducible, peer-reviewable search runs across every database your field expects, with a documented strategy and a clean, de-duplicated library.

  3. 3

    Screening and selection

    Two reviewers screen titles, abstracts, and full texts independently, resolve conflicts, and record every exclusion reason for the PRISMA 2020 flow diagram.

  4. 4

    Extraction and risk of bias

    Piloted extraction forms capture every variable in duplicate, and trained assessors apply RoB 2, ROBINS-I, or Newcastle-Ottawa as your designs require.

  5. 5

    Synthesis and GRADE

    We synthesise narratively or pool quantitatively with the right model, examine heterogeneity, and rate certainty of evidence with GRADE.

  6. 6

    Manuscript and submission

    You receive a PRISMA-compliant write-up, every figure and table, the full audit trail, and support through peer review and reviewer responses.

What researchers say about our systematic review support

A few words from the students, clinicians, and academics we have supported through their reviews.

4.9 / 5 average across 1,194+ delivered projects

I had been struggling with my systematic review for months and was overwhelmed by the screening and data extraction process. The guidance I received was organized, professional, and easy to follow. I finally felt confident moving forward with my research.
Amina S.
Excellent understanding of systematic review methodology. Communication was prompt, and every step of the process was explained clearly. The support I received saved me a tremendous amount of time.
Michael R.
I needed help organizing a complex meta-analysis for my dissertation. The assistance was thorough and methodical, and the final outputs were clearly documented. I appreciated the attention to detail throughout the project.
Grace W.
The literature search strategy was comprehensive and well structured. I was impressed by the professionalism and the commitment to maintaining high methodological standards.
Daniel T.
I had no prior experience conducting a systematic review and felt intimidated by the process. The guidance I received helped me understand study selection, risk of bias assessment, and reporting standards. I would highly recommend these services to researchers needing expert support.
Sophia M.
Working with this team was a smooth experience from start to finish. They were responsive, knowledgeable, and genuinely invested in the quality of my project. My manuscript became much stronger after incorporating their recommendations.
James K.

Systematic review questions, answered

How long does a full systematic review take?

A focused review with a manageable yield is typically delivered over several weeks, while a broad review with a large search yield and meta-analysis takes longer. We give you a realistic schedule with your quote, after we see the question and likely volume of records.

Do you register the protocol on PROSPERO?

We prepare the complete, registration-ready PROSPERO record as a standard part of the protocol stage for health-related reviews. You submit it under your own account, since the registration sits in the review authors' names, and your methods are locked and timestamped before screening.

Can you join a review that is already underway?

Often, yes. We can pick up at the search, screening, extraction, risk-of-bias, analysis, or write-up stage, and we will document what was done before we joined so the final review remains reproducible.

Will the review be reproducible and meet journal requirements?

That is the point of the whole process. Every search is documented, screening is dual and recorded, and reporting follows PRISMA 2020, so the review withstands editorial and peer scrutiny.
