Charlesworth Author Services vs Research Gold

Charlesworth Author Services and Research Gold answer different questions for an academic author. Charlesworth Author Services is an editing and author-services brand: they polish manuscripts, translate text, and prepare submission-ready files. Research Gold is a systematic review writing service and methodology firm: PhD methodologists run the full PRISMA 2020 pipeline including PROSPERO-registered protocol, multi-database literature search, dual-reviewer screening, RoB 2 or ROBINS-I, meta-analysis where appropriate, and GRADE certainty rating. If you need language editing, Charlesworth Author Services is the right partner. If you need someone to run the systematic review itself, see Research Gold's PhD-led systematic review support. For authors who only need the language layer, Research Gold also offers in-house academic editing and scientific manuscript translation.

How Charlesworth Author Services and Research Gold compare at a glance

The honest framing is that the two services solve different problems:

• Charlesworth Author Services is an editing brand built to polish text the author has already written.
• Research Gold is a methodology firm built to run the systematic review from protocol to publish-ready manuscript.

The comparison is therefore not editing-vs-editing or methodology-vs-methodology. It is a question of which problem you currently have. The sections below walk through pricing, turnaround, scope, and the right way to combine the two when both layers matter.

What each service actually does

Charlesworth Author Services is a UK-based author services brand with deep specialism in supporting Chinese, Japanese, and Korean authors publishing in international English-language journals. Their core offering covers English-language editing, scientific translation from Chinese/Japanese/Korean to English, journal selection guidance, illustration polish, and submission support. They partner with multiple society and journal partners across the major publishers and have a strong reputation among authors publishing across Asia-Pacific.

Research Gold's systematic review writing service runs the entire evidence-synthesis pipeline. PhD methodologists draft the PROSPERO protocol, design and execute a multi-database search across MEDLINE, Embase, Cochrane, CINAHL, and Scopus, run dual-reviewer screening in Rayyan or Covidence, extract study data into structured tables, run risk of bias assessment with RoB 2 (randomized) or ROBINS-I (non-randomized), run the meta-analytic synthesis in R (metafor, meta) or Stata with reproducible code, build the GRADE certainty profile, and ship a publish-ready manuscript with all methods, results, tables, and figures.

Where the boundaries fall

Charlesworth does not write systematic reviews. The service is built around polishing finished manuscripts and translating already-written text into English. They do not register protocols on PROSPERO, do not run literature searches across MEDLINE, Embase, or Cochrane, do not screen citations with two independent reviewers, do not extract data, do not run risk of bias assessment, do not run meta-analysis statistics, and do not build evidence-synthesis tables. Their value sits at the language and formatting layer, not the methodology layer.

Pricing transparency

Charlesworth uses per-word tier pricing for editing and translation, with public quote tools on their website. Translation pricing is typically higher than editing alone given the language-pair specialism. Research Gold publishes a starting price of $895 for the systematic review writing service and $750 for the scoping review writing service. Visit the pricing page for the full tier breakdown.

Turnaround time

Charlesworth turnaround runs from 48 hours to 10 working days depending on tier and document length. Translation projects sit at the longer end. Research Gold turnaround for a full systematic review writing service runs 1 week (Gold), 2 to 3 weeks (standard), or 4 to 5 weeks for the deepest tier with meta-analysis and GRADE certainty assessment.

Methodology coverage that only Research Gold provides

The Research Gold methodology stack covers what an editing-only brand cannot:

• PROSPERO registration with a stamped protocol PDF.
• Search strategy in PRESS-checked PubMed, Embase (Emtree), Cochrane CENTRAL, CINAHL, and Scopus.
• Dual-reviewer screening in Rayyan or Covidence with a recorded conflict-resolution log.
• Data extraction into a structured table reviewers can verify.
• Risk of bias assessment with RoB 2, ROBINS-I, or QUADAS-2 depending on study design.
• Meta-analysis in R or Stata with reproducible code and forest plots.
• Heterogeneity diagnostics (I-squared, tau-squared, prediction intervals).
• Publication bias diagnostics (funnel plot, Egger's test, trim-and-fill).
• GRADE certainty profile and a summary of findings table.
• Publish-ready manuscript in IMRAD format with a PRISMA 2020 flow diagram.

If you need any one of these, an editing brand cannot help you.

When to pick Charlesworth Author Services

Pick Charlesworth when your manuscript is fully drafted (or drafted in Chinese, Japanese, or Korean and needs scientific translation into English), and what you need is a publisher-relationship-savvy editor to polish the language and prepare the submission package. They are particularly strong for authors targeting an English-language journal from an East Asian institution.

When to pick Research Gold

Pick Research Gold's systematic review writing services when you need someone to run the full PRISMA 2020 evidence-synthesis pipeline end-to-end. The service is the right fit when you have a research question but no protocol, when you have stakeholders waiting on a published review for a journal deadline, when your team does not have a methodologist or biostatistician on staff, when the project requires a meta-analysis with GRADE certainty, or when peer reviewers have flagged methodology gaps in a previous draft. The team is named PhD methodologists with peer-reviewed publication records, the deliverable is a publish-ready manuscript with reproducible R or Stata code, and the pricing page lists the starting tier of $895.

Decision matrix

When neither is the right answer

If you have a methodologist on staff, an institutional research librarian, a statistician, and twelve months of protected time, you may not need either vendor. A self-led project from a well-resourced research team can produce a publishable review without external help. The question to ask before paying anyone is: do we have the search strategy expertise, the risk of bias rater, the meta-analyst, and the manuscript writer internally? If any one of those four is missing, the project usually stalls.

What to ask any systematic review vendor before paying

Use this short checklist with every vendor (including Research Gold):

1. Do you publish a starting price on your website, or only after intake?
2. Will you register a PROSPERO protocol under my authorship?
3. Which databases will you search? (MEDLINE, Embase, Cochrane, CINAHL, Scopus, others?)
4. How many reviewers screen each citation? (Single-reviewer screening is a methodological red flag.)
5. Which risk of bias tool will you use, and who is the named rater?
6. If meta-analysis is in scope, do you ship reproducible R or Stata code?
7. Will you build a GRADE certainty profile and summary of findings table?
8. What is the named methodologist's publication record?
9. What is the revision policy if reviewers request changes?
10. Is the deliverable a publish-ready manuscript, or only a methodology report?

How to combine Charlesworth Author Services and Research Gold in one publication workflow

A clean two-step workflow: Research Gold writes the full systematic review or meta-analysis manuscript with PRISMA 2020 compliance and a publish-ready statistical appendix, then you pass the English-language draft through Charlesworth's editing tier for an extra polish before submission. For authors at Chinese or Japanese institutions, this combination produces a manuscript that reads fluently to a native-English reviewer while the methodology layer holds up to Cochrane standards.

Where Research Gold fits in your project

Research Gold is the methodology-first option in this comparison. The starting price for a systematic review writing service is $895, the team is named PhD methodologists with peer-reviewed publication records, and the deliverable is a publish-ready manuscript with reproducible R or Stata code, a PRISMA 2020 flow diagram, and a GRADE certainty profile when meta-analysis is in scope.
