Why our guides cite the studies they reference
Search results for sleep medicine are dominated by content marketing from device vendors, supplement companies, and SEO farms. Most of what ranks on the first page isn't wrong, but it's usually shallow — and occasionally dangerous. Patients acting on bad information delay diagnosis by months or years.
Every article on this site is written or reviewed by our board-certified sleep medicine physicians. Specific claims (prevalence rates, treatment efficacy, drug interactions, surgical success rates) are cited to primary sources: AASM clinical practice guidelines, ACP recommendations, peer-reviewed studies in Sleep, CHEST, and JAMA, and FDA-approved device documentation.
When something is uncertain, we say so. When the evidence has changed in the last few years (Inspire therapy outcomes, GLP-1 effects on OSA, central apnea management), we update the article and date the update.

Every guide is signed off by a physician credentialed in sleep medicine.
Primary sources cited
AASM, ACP, peer-reviewed journals, and FDA device documentation.
