Key updates made to the COBRA model released in July 2013:
- Benefits of avoided adult mortality are now estimated using Krewski et al. (2009) and Lepeule et al. (2012). Laden et al. (2006) is no longer used in COBRA.
- There are changes in the set of health impact functions for two morbidity endpoints: asthma ER visits and all respiratory hospital admissions.
- Unit values for Asthma Exacerbation, Lower Respiratory Symptoms, and Asthma Exacerbation, Upper Respiratory Symptoms are now based on one symptom-day each.
- Recent mortality, hospital admissions, and emergency room visits incidence data has been added.
For more information about the updated model and all of its assumptions, see the User Manual.
