Research & Writing
Our editorial team researches and writes every calculator explainer and Wellness Hub guide. We ground each one in peer-reviewed studies and primary sources (CDC, WHO, ACOG, AHA, and the published literature), link those sources openly, and revisit articles as the evidence changes.
How we research, write, and review content is documented in our editorial policy and methodology.
