  1. *Utility scores were obtained using the Assessment of Quality of Life (AQoL) instrument.
  2. †Obtained from AQoL publication [17] and based on equivalent midpoint age used in the model. The normal population for age less than 55 comprises estimates for the 30-39 age group. This is because the midpoint for NEMESIS cases in the < 55 age group was 33 years. Utility estimates in the other age bands result from normal population for ages 50-59, 60-69, 70-79 and 80+, respectively.
