%description
Implements the 2019 World Health Organization (WHO) cardiovascular disease
(CVD) risk prediction models, as described in Kaptoge et al. (2019)
<doi:10.1016/S2214-109X(19)30318-3>. Provides two validated models for
estimating 10-year risk of fatal and non-fatal cardiovascular events
(myocardial infarction and stroke): a laboratory-based model using age,
sex, systolic blood pressure, total cholesterol, smoking status, and
diabetes history; and a non-laboratory-based model substituting body mass
index (BMI) for cholesterol and diabetes, suitable for resource-limited
settings. Risk estimates are recalibrated to 21 Global Burden of Disease
regions using region-specific incidence rates and risk factor
distributions derived from the Emerging Risk Factors Collaboration.
Functions are fully vectorized for efficient batch calculations and
support automatic country-to-region mapping via ISO 3166-1 alpha-3 country
codes.
