  1. Mean 95% Crl are given for non-screening scenarios with treatment rates from 60% to 100% combined with different ratios of bracing to surgery from 20/80 to 70/30.
  2. Non-screening is more expensive with higher treatment rates and higher surgical rates compared with screening. Non-screening is less expensive with lower treatment rates and higher bracing rates compared to screening.
