  1. The incremental cost was highest in the 90% treatment rate non-screening scenario with probability of being > 0 close to 100%. Incremental cost in non-screening Norway 2012 is close to the 70% treatment rate scenario. Incremental costs were higher in all non-screening scenarios when comparing screening of girls only than when comparing to screening of both boys and girls. The probabilities of incremental costs being >0 are also higher when comparing non-screening scenarios to screening of girls only than for both boys and girls combined.
