How We Evaluate Medical Evidence
We do not summarize unverified secondary blogs or forum discussions. Our research team relies exclusively on clinical consensus guidelines, systematic reviews (such as Cochrane Database of Systematic Reviews), and peer-reviewed clinical trials. When biological nuances or failure rates are discussed (such as typical-use vs. perfect-use failure rates for contraception), we cite primary epidemiological registries.
