Accuracy, traceability, and limits come before polish.

Source hierarchy

RxTray prioritizes original equations and validation studies, current professional guidelines, government and regulatory sources, official product labeling, and authoritative clinical references. Secondary summaries may help with context but should not replace the controlling source.

Calculation standard

Inputs, units, coefficients, conversions, rounding, and model assumptions must be explicit. Automated test cases check the implementation, but passing software tests is not the same as clinical validation.

Limitations and uncertainty

Known exclusions, disputed methods, restricted populations, and important alternatives are published with the tool. RxTray does not hide uncertainty to make a result appear simpler.

Use of automated and AI-assisted tools

Automated systems may assist with research organization, drafting, code generation, test generation, or consistency checks. They are not treated as clinical reviewers or authoritative sources. Published clinical claims must be traceable to cited evidence, and material calculation logic must be covered by reproducible tests and human release review.

Commercial independence

Advertising or sponsorship must be clearly labeled, separated from calculations and results, and must never determine formulas, interpretations, rankings, citations, or clinical conclusions. The full rules appear in the Advertising, Sponsorship, and Affiliate Policy.
