About and methodology | Maternal & Newborn Atlas

Not reviewed by clinicians

This atlas has not been reviewed or approved by clinicians. No doctor, nurse, midwife or other clinician checks its pages before they are published.

It summarizes published sources, such as research papers, trial registries, regulators and guidelines, for general information. It is not medical advice, and it cannot tell you what is right for your own health or for anyone else's.

Sources can be out of date, and the atlas can make mistakes when it summarizes them. Every claim names its sources and the date they were retrieved. Check them before relying on anything here.

Talk to a qualified health professional about your own care. In an emergency, call your local emergency number.

To report a mistake, see Corrections.

Methodology

Each page describes one named thing: a condition, an intervention, a study and so on. Pages begin in plain language and then give the technical detail.

The records behind the pages are JSON files in Git. A build checks their structure, resolves every reference and then writes this website and its data downloads together as one release.

A medical fact appears only with a source that was fetched, with its retrieval date and a hash of what was retrieved. A claim also names the population, setting and follow-up it applies to. Maternal, fetal and newborn contexts stay separate, and a missing value is shown as "Not reported", never as zero.

The build checks structure. It does not check whether a claim is clinically true.

Review policy

No clinician reviews the pages of this atlas before they are published. The atlas publishes every page and claim that is not retired, and any of them may change. The disclaimer at the top of this page applies to all of them.

This public release includes every record that is not retired.

Reuse terms

The atlas's own text and curation may be reused under Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0, https://creativecommons.org/licenses/by-nc/4.0/): credit the atlas, and do not use it commercially. See the atlas About page. The release metadata and every download carry the same statement, with the id CC-BY-NC-4.0.

Read the Creative Commons Attribution-NonCommercial 4.0 International license.

Text quoted from a source stays under that source's own terms, given as the source's reuse_basis. The atlas's reuse terms do not cover it. The downloads list each quotation with its source in third_party_quotations.

Corrections

To report an error or a missing source, fill in the correction form on GitHub (a free GitHub account is needed) and name the page or record id. Please do not include personal health information. Each page also has its own correction link.

Data and downloads

Everything on these pages is also available as data from the same release. Every download carries the release id, the build time, the input and engine commits, and the reuse terms above. Text quoted from a source is marked with its source and keeps that source's terms.

Every page also links its own files: the entity as JSON (/api/v1/entities/{id}.json), each claim as JSON (/api/v1/claims/{id}.json) and the page as Markdown for software agents (/api/v1/context/{id}.md).

In file names, the id cardio:example is written cardio--example, because a colon is not safe in a file name or a relative link. Split on the first -- to get the id back.
