• Importance: Interventions that addressed a problem of health significance, measured by the burden of disease.
• Impact: Interventions or programs that demonstrated a clear and measurable impact on the health of a population.
• Duration: Interventions or programs that functioned "at scale" for at least five consecutive years.
• Cost-effectiveness: Interventions or programs that used a cost-effective approach, using a threshold of about US $100 per disability-adjusted life-year saved.
