References & Sources
My Medicine Advisor draws its health information from recognised medical authorities and peer-reviewed research, and the calculators use established, published formulas. This page lists the main sources behind our content and the equations behind our tools, so you can check them yourself.
How We Source Our Content
This page explains where our health information comes from and how we try to keep it accurate. (Our content is educational — see the Medical Disclaimer.)
Evidence First
We aim to base medical claims, tool formulas, and clinical figures on recognised authorities, peer-reviewed literature, or official datasets — not on opinion pieces or uncited blogs.
Linked So You Can Check
Where we rely on a source, we try to link to it, so you can go straight to the original and verify a claim for yourself rather than taking our word for it.
AI Never Invents Sources
Content is drafted with AI assistance, but AI is never used to generate or fabricate references. Any source is checked against the actual primary material before it’s published.
Dated & Updated
Pages carry a visible “last updated” date, and we revisit content as guidelines change or when something is flagged as out of date.
Published Tool Formulas
The calculators use established equations from the published literature — listed in full in the formula table further down this page, with their source.
Corrections Welcome
If you spot an out-of-date reference or a broken link, tell us and we’ll fix it — see our Corrections Policy.
The Evidence Hierarchy We Aim to Follow
Not all evidence is equal. Where possible, we lean on the stronger forms of evidence over weaker ones, and we don’t treat uncited blogs as medical sources.
Systematic Reviews & Meta-Analyses
The strongest level of evidence — analyses that pool many studies. Examples: Cochrane Reviews, large meta-analyses.
Clinical Practice Guidelines
Evidence-based recommendations from major authorities — WHO, CDC, NICE, AHA, ADA, ACOG.
Randomised Controlled Trials
The gold standard of primary research, published in indexed journals such as NEJM, JAMA, Lancet, and BMJ.
Cohort & Observational Studies
Population-level studies, useful when randomised-trial evidence isn’t available.
Expert Consensus & Case Series
Used when higher-level evidence isn’t available, and noted as such.
Uncited Blogs & Anecdotal Reports
Not used as medical sources.
Authorities We Draw On
The main public-health and research bodies our content relies on — all linked so you can go straight to the source.
World Health Organization
Global public-health guidelines, disease information, and clinical standards.
Centers for Disease Control and Prevention
US clinical guidance, vaccination schedules, and public-health data.
National Institutes of Health
Biomedical research, disease information, and clinical resources.
National Library of Medicine
The largest biomedical literature database — where we check journal citations.
National Institute for Health & Care Excellence
UK evidence-based clinical guidelines for treatments and diagnostics.
Indian Council of Medical Research
India-specific clinical protocols, advisories, and epidemiology data.
Where a topic falls within a specialty, we look to the relevant society’s published guidance:
American Heart Association (AHA)
Blood-pressure thresholds, lipid guidance, cardiovascular risk.
American Diabetes Association (ADA)
Diabetes risk, HbA1c thresholds, metabolic criteria.
American College of OB/GYN (ACOG)
Pregnancy, fertility, and reproductive-health guidance.
American Academy of Dermatology (AAD)
Skin-condition information and treatment guidance.
American Psychiatric Association (APA)
Screening-tool criteria (PHQ-9, GAD-7, WHO-5) and DSM-5.
ASCO
Cancer staging and treatment guidance.
ERS & ATS
Respiratory guidance — COPD, asthma, spirometry.
AAOS
Joint, bone, and musculoskeletal guidance.
Peer-Reviewed Journals
Where we cite primary research, it generally comes from established, peer-reviewed journals indexed on PubMed.

How a Source Gets Checked
It’s a simple, honest process — one editor, primary sources, and links you can follow.
Research
The topic is researched starting from primary authorities and peer-reviewed literature
Draft
The article is drafted with AI assistance, then read and edited by a person
Check Against the Source
Claims are checked against the original source — not an AI-generated reference
Link & Date
The source is linked where possible, and the page is dated so you can see how current it is
