Your expertise, turned into a publication.

Invited reviews, clinical updates, state-of-the-art reviews, and editorials, structured around a clear argument rather than a search protocol. Fast to produce, well cited, and the practical route to a paper when you have no dataset in hand but an editor's deadline.

What it is

An argument, built on the evidence.

A narrative or state-of-the-art review synthesises what is known on a clinical topic into a coherent, expert account: where the field stands, what the landmark trials and guidelines say, where the evidence conflicts, and what should happen next. Unlike a systematic review, it is not defined by an exhaustive search and pooled analysis, it is defined by the quality of its argument and the judgement behind it.

What it is built for

Formats, invited and state-of-the-art reviews, clinical updates, editorials, commentaries, and viewpoint pieces.

When, you hold expertise on a topic, an editor has asked, or a field has moved and needs a clear account, and no dataset is required.

Not for, questions that need a pooled effect estimate; those are systematic reviews and meta-analyses, which we also run.

1

Scope the review

We agree the topic, the angle, the target journal, and its review format, or work from the editor's invitation.

2

Outline

We produce a section-by-section outline with planned tables and figures for your approval.

3

Evidence map

We run and document the targeted search and build the reference library.

4

Draft

We write the full draft with you, iterating on the argument and the balance of evidence.

5

Figures & polish

Tables, figures, a central illustration where the journal wants one, and the integrity check.

6

Submit & revise

We package the submission and answer reviewers with you to a decision.

Standards we work to
