The results of the PSA are displayed as a scatterplot of incremental costs and incremental effects and as cost-effectiveness acceptability curves.
For each of these bootstrapped samples, the incremental costs, incremental effects, and the incremental cost-effectiveness ratio (ICER) will be calculated.
Outcomes with their surrounding uncertainty are presented for IC, incremental effects (IE) and the incremental cost-effectiveness ratio (ICER).
The outcome of this CEA is expressed as a ratio of incremental costs relative to incremental effects of the intervention: the incremental cost-effectiveness ratio (ICER), expressed in euros per QALY Quality Adjusted Lifee Years [14]].
Presenting the results of cost effectiveness studies requires reporting the incremental costs and effects of a new intervention relative to an alternative and then reporting an incremental cost effectiveness ratio (incremental costs divided by incremental effects).
By giving incremental effects for different patient subgroups, we support comparative effectiveness research (CER) on osteoarthritis interventions.
The incremental cost-effectiveness ratios (ICERs), comparing incremental costs with incremental effects, were calculated on the efficiency frontier.
By giving incremental effects for different patient subgroups, we support future comparative effectiveness research on osteoarthritis interventions and across countries.
Substitution of the incremental costs (€797) and the incremental effects (0.12) in the formula for the incremental costs effectiveness ratio, indicates that the corresponding mean ICER is €6,642 per three months PD-free survival time for the factual condition.
26 For the cost effectiveness analyses, we calculated the incremental cost effectiveness ratios by dividing the incremental costs by the incremental effects.
Figure 2 and online supplementary figure S1 show the cost-effectiveness planes comparing the joint density of incremental costs and incremental effects for 10 000 model iterations.
