Cost-effectiveness plane and cost-effectiveness acceptability curve.
The modelled analysis indicated that the mean cost difference between study groups would have been reduced if the fixed costs of the intervention had been attributed to the original target population of 200 people. Savings in total cost was calculated as $2,532 (95%CI -8126; 3061); though not statistically different, the total cost was lower in the intervention group. The modelled analysis based on the variation of fixed costs over 200 people, the ICER was calculated as a savings of $28,189 per QALY, favouring the intervention group.
