  1. *The intervention and its costs affect the entire population and cannot be targeted such that only one subgroup is affected. Therefore, cost per QALY results are not reported by sex. Results presented are the median values from 2000 iterations of a Monte Carlo simulation, as such, the numbers in the final column may not equal the sum of males and females; 95% uncertainty intervals in parentheses; QALY, quality adjusted life year
