روش‌ها و عدم قطعیت

The methods سامانه‌ها Science and Modelling relies on: their equations and assumptions, the data they need, how they are validated and the limits of what they can show.

Methods and uncertainty: PRISMA 2020 review reporting

PRISMA 2020 is a reporting guideline for systematic reviews; the steps follow its checklist, not a mandated sequence, and no Nexus document adopts it.

  1. 01 Plan

    1. 01Registration and protocolRecord · The review teamThe guideline asks for registration details, access to the protocol and any amendments.
    2. 02Eligibility criteriaRecord · The review teamThe guideline asks for the inclusion and exclusion criteria and how studies were grouped.
  2. 02 Find and select

    1. 03Search: sources and strategiesStep · The review teamThe guideline asks for the information sources and the full search strategies. It does not fix which sources are used.
    2. 04Selection of studiesStep · The review teamThe guideline asks how studies were judged eligible, including how many reviewers screened. It does not fix the number of reviewers.
    3. 05Flow diagramسابقهThe flow diagram shows the number of records found, the number of studies included and the reasons for exclusion.
  3. 03 Analyse

    1. 06Data collectionStep · The review teamThe guideline asks how data were collected from reports and which data items were sought.
    2. 07Risk of biasStep · The review teamThe guideline asks for the methods and tools used to assess risk of bias.
    3. 08SynthesisModel · The review teamThe guideline asks for the effect measures and the synthesis methods. It does not prescribe meta-analysis.
    4. 09Certainty of evidenceStep · The review teamThe guideline asks for the methods used to assess certainty, and reports the result per outcome. It does not name a grading scale.
  4. 04 Report

    1. 10Review reportسابقهThe guideline helps authors report why the review was done, what they did and what they found.

گزارش‌هاOutline of an externally published reporting guideline, not a Nexus process and not a record of operation. PRISMA 2020 mainly covers reviews of intervention effects. No Nexus page names it. Every programme is at service level R0.

06How uncertainty is reported

How uncertainty is reported.

  1. 01

    State assumptions

    Each analysis lists its assumptions and the data it depends on.

  2. 02

    Quantify where possible

    Ranges and confidence are reported alongside central estimates.

  3. 03

    Validate and compare

    Models are checked against observations and, where possible, against other models.

  4. 04

    Publish limits

    What an analysis cannot show is stated beside what it can.
