Choose the result you need, then scope the work and fees.
Topic appraisal explains whether and how to proceed. A research module delivers the actual results of one agreed stage. A complete study delivers a report, data and code. Manuscript drafts and submission materials are optional, with fees and revision rounds itemised in the same quote.

Choose the deliverable you need
Inspect the value and deliverables, then agree scope, review and fees.
Three deliverables: a topic decision, results from one research stage, or a complete study. Full studies include a report, data and code; manuscript drafting, submission materials and revisions are separately priced options.

Topic appraisal & study design
Is the question duplicated, feasible and worth the effort?
Core valueBuy a topic decision and study design before committing to execution.
What you receiveUse the research landscape to decide whether to proceed, narrow or pause.
Review and primary-study landscape
Evidence gaps and feasibility memo
Methods scope and effort estimate
PDF and study-map spreadsheet; retain search scope and reasoning.
How fees workReference: CNY 5,000–15,000 per question appraisal
Pay after agreeing appraisal scope; stop after appraisal, with reusable work credited if continuing.
Scope limits
Excludes full retrieval and screening, analysis results and a manuscript.
The study needs end-to-end execution and coordinated review.
Core valueBuy a complete, reviewable and reproducible SR/Meta study package.
What you receiveDeliver a full study in stages, from protocol to synthesis and handover.
Protocol, screening and extraction registers
Risk-of-bias appraisal and synthesis report
Data, code and reproducible delivery package
Protocol and milestone acceptance; no promise of positive findings or publication.
How fees workDefined projects: CNY 60,000–150,000 reference; large studies quoted separately
Pay by accepted milestones from appraisal to handover. Report, data and code are included; manuscript drafting, submission materials and revisions are separately quoted options.
Scope limits
Fees are independent of positive findings or publication acceptance; a manuscript is not included by default.
Amounts are proposed references or examples. Formal quotes depend on inputs, questions, professional review and acceptance scope. Agree updates separately; the same work is not charged twice.
What inputs are needed?
Which output do you need?
A topic-decision package, results from one stage, or complete research outputs
Existing work and review

Do you want manuscript support?
Reports, data and code are default. Agree draft manuscripts, submission materials, revisions and author contributions separately
