How the audience is built
Patient counts for AFib stroke prevention & VTE come from physician-reported registries, diagnostic population surveys, and federal (CDC, CMS, NIH) and disease-association reporting, listed above. Each of 251.7M U.S. adult records is scored 0 to 100 for fit to those published patient profiles by age, gender and income, weighted by geographic prevalence (CDC PLACES: High Blood Pressure (BPHIGH)). Qualified means a score of 57 or higher. High-fit means 63 or higher.
How quality is confirmed
Audience quality has historically been confirmed through holdout sampling: a delivered audience is compared with the full national panel at the same fixed score cutoffs, and the difference is reported as lift. During a campaign, the same comparison runs every week on the households actually reached.
What it is not
Qualified audiences are not built from modeled claims data extrapolated from a few locations. They come from peer-reviewed, population-level public health reporting on patient profiles and population surveys. No diagnosis records, claims, prescriptions or PHI are used, and the score says nothing about any one person's health.
