Editorial process

1. Topic selection

We choose calculators where (a) there is a validated, peer-reviewed formula or instrument, (b) the topic is searched for in plain language by non-clinicians, and (c) we can credibly explain the result and its limits.

2. Drafting

A first draft of each calculator (formula, classification thresholds, FAQ, sources) is written by the editorial team and cross-checked against at least two independent authoritative sources — peer-reviewed literature, official clinical guidelines (NICE, USPSTF, WHO, CDC, NHS, Polish Medycyna Praktyczna), or government health bodies.

3. Source verification (instead of medical review)

We do not employ medical reviewers. Every claim is instead traced back to a named primary source — peer-reviewed paper, official guideline, or government health body publication — and that source is cited inline with publisher and retrieval date. The reasoning, and the calculations we explicitly will not publish, are detailed in our methodology.

4. Update cadence

Calculators are re-reviewed at least every 12 months, and immediately when (a) the source guideline is updated, (b) a published study substantively changes the underlying evidence, or (c) a reader flags a meaningful issue. The "Last updated" date on every page reflects the most recent review.

5. Corrections

We do not operate a support inbox, so we cannot promise an individual reply — see contact. Errors are caught by the cadence in section 4: each calculator is re-checked against its source list, and any claim that no longer matches its primary source is corrected. When we correct a page, we re-verify every source on it and move the "Last updated" and "Sources verified" dates at the top of that page. Those dates are the public record of the correction; we do not maintain a separate changelog.

6. AI use disclosure

We use AI to assist drafting, formatting, and translation. Every AI-assisted passage is checked by a human editor against the primary sources cited on the same page before publication. AI is never used to generate medical claims, citations, or interpretations without verification against primary sources. As stated in section 3, no step of this process involves a medical reviewer, because we do not employ one.
