Evidence Synthesis

Systematic Reviews & Evidence Synthesis

Rigorous evidence synthesis for researchers and postgraduate students — from protocol and search strategy through screening, extraction, and synthesis to a manuscript-ready review.

Start a scope reviewView pricing

This service fits when

  • You need a systematic review or meta-analysis for publication in a peer-reviewed journal.
  • Your graduate program requires a rigorous evidence synthesis chapter or a standalone review.
  • You need a scoping review to map an emerging field before committing to a study.
  • You started a review and need it completed to a publishable standard.

What this service solves

A defensible evidence synthesis requires a reproducible search, consistent screening, disciplined extraction, and transparent reporting. Most reviews fail peer review on process, not topic: undocumented searches, inconsistent eligibility decisions, and numbers that cannot be traced. This service produces the review — and the audit trail behind it.

How this service runs

  1. 01

    Scope review

    We clarify the question, feasibility, and the right review type. Free of charge.

    Written scope

    Review type, databases, deliverables, timeline, and a fixed price — approved by you before work begins.

  3. 03

    Protocol & search

    Eligibility criteria and a documented, reproducible search across the agreed databases.

  4. 04

    Screening & extraction

    Consistent eligibility decisions and disciplined data extraction, fully documented.

  5. 05

    Synthesis

    Structured narrative synthesis, or meta-analysis with forest plots where the data permit.

  6. 06

    Quality control & verification

    The full check set below, plus authenticity screening where included.

  7. 07

    Delivery & revision

    Complete package delivered; one structured in-scope revision round included.

Quality controls for this service

  • Search reproducibility — strategies re-run and reconciled against reported counts
  • Eligibility consistency — screening decisions checked against the stated criteria
  • Extraction spot-verification against source studies
  • Citation integrity — every reference corresponds to a real, checkable source
  • Numerical reconciliation across text, tables, figures, and the PRISMA flow
  • Reporting-standard checklist completed — PRISMA 2020 / PRISMA-ScR

Full detail: Quality & Verification

Verified

  • Originality and AI-content screening through Copyleaks, with the certificate delivered — where included in scope
  • Citation traceability — any reference can be followed to its source

Not guaranteed

  • Journal acceptance or peer-reviewer opinions
  • That pooling will be statistically appropriate — if meta-analysis is not defensible, we say so and document why

All project material is handled under our confidentiality policy — project-team access only, no reuse, deletion on request.

Turnaround

Depends on review breadth and the number of eligible studies. The timeline is fixed in your written scope before you commit.

Pricing

Driven by databases covered, expected record volume, synthesis type (narrative vs meta-analysis), languages, and timeline. Free scope review; fixed written quote.

Revisions

One structured revision round within the approved scope is standard. Out-of-scope changes are re-quoted in writing — never silently billed.

Systematic Reviews & Evidence Synthesis — questions

Can you do a meta-analysis?

Yes — where the included studies report compatible data. If pooling is not statistically defensible, we say so, document why, and deliver a structured narrative synthesis instead.

Do you register the protocol on PROSPERO?

We prepare the registration-ready protocol. Registration itself is completed under your name, because registries record the review team's identity.

Which reporting standard do you follow?

PRISMA 2020 for systematic reviews and PRISMA-ScR for scoping reviews, unless your journal or institution mandates a different standard.

Can you finish a review I already started?

Yes. We audit what exists, state plainly what can be kept, and scope only the remaining work.
