START WITH YOUR SITUATION

Find a plan for the task you face now.

Choose a situation like yours. See what the investment addresses, what is delivered and which useful assets you keep.

You have an idea. Validate it before launching a study.

You have an initial topic or a MetaQuant candidate with a stated data cutoff; recent reviews, registrations and independent usable data still need checking.

CNY 5,000–15,000 per topicSee the deliverable

Research teams

Your data are verified. Finish a defined analysis module.

Your team has screened, extracted and verified the data but is stuck on effect selection, study dependencies, missing information or conventional analysis and interpretation.

From CNY 3,000 per moduleSee the deliverable

Research teams

Your question and scope are clear. Commission the complete review.

Your main question and intended use are defined. You need the protocol, search, screening, extraction, appraisal and analysis completed under consistent rules, with agreed human review.

CNY 60,000–150,000 per defined systematic review or meta-analysisSee the deliverable

Research teams

A complete-study scale scenario: execute and review a large volume at milestones.

Many records and full texts, complex study dependencies and multiple teams require common rules, clear responsibilities and staged handover of sources, data and versions.

Large: CNY 200,000–600,000; very large: CNY 500,000–1,500,000+See the deliverable

THE BASIS FOR THIS SCOPE

Why this approach? Inspect the basis.

Trace a clinical question to the research and distinguish effect size, certainty and the population.

PUBLIC DATABASE

PubMed

NLM / NIH

Check papers, abstracts and original sources

Find literature for a clinical question and inspect authors, publication dates, abstracts and full-text links.

Scope & access conditions

PubMed provides citations and abstracts, not journal full text. Access depends on the publisher or archive.

PUBLIC DATABASE

Cochrane

Read systematic reviews and plain-language summaries

Explore a question’s research synthesis and the confidence researchers have in the findings.

Scope & access conditions

Plain-language summaries are public; full-review access varies. Applicability still depends on the population and question.

METHOD REFERENCE

GRADE · Cochrane Handbook

Cochrane · Chapter 14

Show effect size and confidence separately

Present important outcomes, relative and absolute effects, available data and certainty, with reasons for downgrading.

Scope & access conditions

GRADE evaluates a body of evidence for a particular outcome. Database inclusion or one study does not automatically establish high certainty.

Open official source

These references support problem definition and evidence appraisal. Your conclusions still require project-specific sources and professional review.
