Santen and colleagues’ 2020 paper is a case-based clinical review of personalized postmenopausal care. It should not be mistaken for a complete statement of current 2026 guidance.
Different sources do different jobs
An original research study reports what investigators observed or tested. A review synthesizes multiple studies. A professional guideline weighs evidence to recommend clinical approaches, often with attention to certainty and applicability. A news article summarizes a development for readers and may omit important conditions or limitations.
The 2020 paper helps explain clinical reasoning: symptoms, contraindications, baseline risk and patient preferences are considered together.
Study design changes what you can conclude
Randomized trials compare assigned treatments and can reduce confounding. Observational studies examine people’s real-world experiences, but groups may differ in ways that influence the result. Both contribute to clinical understanding, though they do not provide identical kinds of evidence.
Santen and colleagues explicitly acknowledge this issue when discussing hormone routes and extrapolating WHI findings. Their risk figure contains trends that were not statistically significant. Reproducing the numbers without those qualifications would make the paper appear more definitive than it is.
Why guidance changes over time
New trials, longer follow-up, new products and updated labeling can change clinical practice. An older source can remain useful for background while no longer being the right source for a current prescribing rule.
These companion pages use the supplied 2020 clinical review to explain concepts and questions for a consultation. Historical calculator thresholds and medicine lists are identified as dated rather than promoted as current instructions. The FDA labeling change discussed in the main guide is a separate, dated development; it does not eliminate the need for individual assessment.
- Look for a publication date and identify whether the source is primary or secondary.
- Ask whether a more recent guideline or product label changes the recommendation.
- Distinguish a research finding from a recommendation to start treatment.
