Authorized case or research data need a defined preparation or analysis stage completed.

Variables, missingness, descriptive work or synthesis are blocking the team’s deliverables.

How does this scope address your concerns?

I want verifiable results, figures and code, rather than storage or a predetermined positive finding.

When this scope fits
  • Permissions and research purpose are clear, with inputs ready for agreed checks
  • Ability to define variables, outcomes, methods, review and acceptance for one stage
When the scope needs adjusting
  • Unauthorized record uploads or unchecked automated de-identification
  • A complete cohort, SR/Meta or manuscript: define the full commission separately
  • Fabricated follow-up, predetermined significance or automatic causal claims

Scope & acceptance

Work covered by the quote

Research module · same pricing basis as research teams

  • Verified client data; one outcome, up to 20 independent studies, agreed conventional methods and one revision.
  • Includes data-issue records, analysis code, results, agreed figures and one explanatory handover.
  • Case-variable design, cohort cleaning, screening, extraction or extra models require agreed input volumes, hours and review.

Contract for one module and payment milestones. Approve new outcomes, models or input batches first; do not charge the same preparation twice.

  • No case-storage monthly or per-page OCR subscription charge.
  • The entry scope excludes primary extraction, a complete cohort or SR/Meta, manuscript drafting and submission.

Acceptance criteria

  • Accept agreed data checks, methods and module outputs. Code reproduces analysis in the agreed environment; missing or unsuitable data are recorded. Finding direction and publication are not acceptance criteria.

Checking the evidence

  • Retain identifiable original sources, authorised inputs and missing information.
Workflow and inputs

From inputs to delivery

Explore the workflow and deliverable structure. This preview does not run searches, read real records or produce medical findings.

01 / WORKFLOW PREVIEW

Confirm inputs and study purpose

Agree institutional permission, data processing and intended research use. Provide an overview only on this form; a formal intake arrangement is required for real records.

Methods, sources and professional responsibilities
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.

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.

What to assessCovidence / ElicitEvidence OS · Commissioned scope
Service focusCovidence and Elicit provide team screening, source-supported extraction, exports and reviewable workflows. Check their official descriptions for current functionality.Define the stage you need, agree inputs, methods and reviewers, and receive its registers, analyses, figures or code with an issue record.
When to chooseResearch tools suit teams with staff to execute and review the work. Compare commissioned modules by methods, review responsibility and outputs.Proposed CNY 3,000 conventional-analysis example: verified data, one outcome, up to 20 independent studies, agreed conventional methods and one scoped revision. Screening, original extraction and complex analyses are separately scoped.
What the fee pays for
Proposed from CNY 3,000 per defined module. Example: CNY 1,500 at start and CNY 1,500 at acceptance. Quote actual inputs, methods and review hours; clinicians and research teams use the same fee for the same scope.
Value beyond this task
Input-issue records, agreed results, method notes, figures and code for team review and subsequent research.
How to assess value
Compare software, internal hours, professional review and rework for the same module; accept the agreed results and reproducibility materials.

Default delivery covers the agreed module. Manuscript drafts and submission materials are optional and itemised. The entry price does not include a complete review; no promise of significance or acceptance.

Reuse and updates after delivery
  • Buy a research stage the team can continue using, with methods, results and code for subsequent review and writing rather than a conversational summary.

Agree reuse rights, retention and export periods, and future update fees when scoping.

Questions before commissioning

What does CNY 3,000 cover?

An entry analysis module using verified data, one outcome, up to twenty independent studies, conventional methods and one revision. Cohort cleaning or complex models require input-based quotes.

Is a manuscript delivered?

This module delivers agreed data, results, figures and code. A complete study, manuscript, editing or submission materials are included only when separately contracted.

Can I upload real records now?

This form accepts an overview only. Confirm permissions, processing and formal intake first; do not send real medical records through it.

Define the delivery for your actual question.
