How our calculators are built
Our calculators are designed using formulas and models derived from peer-reviewed medical literature, clinical guidelines, and standard reference sources. Each calculator is programmed to apply these formulas consistently to provide quick educational estimates.
We review sources from reputable organizations such as:
- World Health Organization (WHO)
- Centers for Disease Control and Prevention (CDC)
- National Institutes of Health (NIH)
- Peer-reviewed medical journals
- Standard clinical textbooks and guidelines
Specific references used for each calculator are listed on the individual calculator page where applicable.
Data limitations
Medical calculators rely on population-level research and simplified assumptions. Real-world outcomes may vary due to individual health factors, medical history, and clinical judgment.
Our tools:
- Provide estimates for educational purposes only
- Do not replace professional medical advice
- May not apply to all individuals or situations
Users should consult a qualified healthcare professional for personalized guidance.
Updating and review process
We periodically review our calculators and sources to keep them aligned with current medical knowledge. However, medical research evolves continuously, and we cannot guarantee that all information is always fully up to date.
If you believe a calculator requires correction or updating, please contact us.
