Sourcing Standards

Last updated June 9, 2026.

Everything here comes from free, official, or open-access sources. This is a plain account of what that means.

The news feed and guideline summaries pull from U.S. federal agencies (CDC, NIH, FDA, CMS, HRSA, AHRQ), primary-care and specialty societies with publicly available guidelines (USPSTF, AAFP, ACP, AAP, ACC/AHA, IDSA, ATS, ADA), the WHO where their guidance is standard in U.S. practice, open-access journals indexed in PubMed (NEJM Open, JAMA Network Open, PLOS Medicine, BMJ Open), and ClinicalTrials.gov for trial registrations and result summaries. Paywalled content doesn't go on the site. When a study matters and the full text isn't free, we link the abstract and any preprint that's available.

Guideline summaries

Each summary is written from the primary guideline text itself, not a secondary account of it, and includes the issuing organization, the version year, and the evidence grade where one is reported. Every entry links back to the source. When a guideline is updated, the entry is updated or pulled.

For clinical decisions, go to the current primary source. Summaries can be wrong, and guidelines change.

Landmark entries

The timeline covers studies and events whose findings have held up in practice. Each entry cites the original publication or official source record.

Conflicts

The physician who runs the site has no financial relationships with pharmaceutical companies or device manufacturers, and no financial interest in anything covered here. If sponsorship ever appears on the site, it will be clearly labeled as such and will have no say in what gets covered or how. Not affiliated with or endorsed by any of the organizations it covers.

Corrections

Wrong recommendation, stale guideline, broken link, anything factually off: email theclinicaltimes@protonmail.com. Corrections are made promptly.
