Clear sources, honest limits, accountable updates.

Source hierarchy

For medication and safety facts, Evo starts with current FDA prescribing information and FDA safety communications. For broader health guidance, we prefer NIH and NIDDK material, professional consensus guidance, and peer-reviewed primary research. Product facts come from current labels, manufacturers, and independent certification records; retailer pages are secondary sources for availability and price.

• FDA Drugs@FDA database
• NIDDK health information
• PubMed biomedical literature

Health-content boundary

Evo explains formulas, units, assumptions, label language, and evidence. It does not recommend a medication, choose or change a dose, diagnose symptoms, or promise an outcome. Calculators present estimates and conversions rather than treatment instructions.

Practical safety information is not withheld merely because a topic involves medication. When preparation or measurement varies by product, the page tells readers to use verified label and prescriber instructions rather than transferring assumptions from another product.

Authorship, review, and AI assistance

Current pages are published by the Evo Editorial Team. This group byline describes a publishing function, not a medical credential. Individual researchers, editors, or clinicians will be named only after their identity, role, and relevant scope are verified.

AI tools may assist with research organization, drafting, code, and quality checks. AI assistance does not count as clinical review and does not replace checking factual claims against the sources shown on the page. Evo will not claim human or clinician review that did not occur.

Updates, conflicts, and corrections

A displayed review date changes only after substantive source, method, or content review—not for cosmetic edits. Material corrections should be explained on the affected page when the earlier version could have changed a reader’s understanding or use of a tool.

Commercial relationships, free samples, affiliate links, and sponsor involvement must be disclosed on the affected page. Read the corrections policy for the present reporting limitation and correction process.
