About ProHealthIt

ProHealthIt is an independent educational health information project maintained by Ash K, based in Dehradun, India. His background is technology and independent research; he is not a doctor or licensed medical professional.

Methods and sources

Each tool should explain what it calculates, the reference used, its units and its limits. A published equation or questionnaire does not mean a particular website implementation is clinically validated. No independent clinical review is claimed unless a named qualified reviewer and the actual review scope are documented.

Recent corrections include unit conversion, lean-mass arithmetic, CDC/WHO growth data, EPDS scoring and overnight sleep arithmetic. Unsupported custom risk scores and personalized outputs have been withdrawn or replaced with clearly labelled educational guidance. The previous blanket claims that all methods were exact and every claim came only from primary sources have been removed.

Editorial standards

1. Identify the exact source, applicable population and version.
2. Check consequential calculations with independent reference cases, including units and boundaries.
3. Keep instructions, results, articles and metadata consistent.
4. Explain uncertainty and seek qualified review where clinical interpretation is needed.

These are maintenance standards, not a claim that every legacy article has completed a clinical review. Updated dates indicate a content or method change, not medical approval.

Privacy and independence
