The ICER based on the incremental cost per QALY saved between study groups was a cost of $7,933 per QALY saved. The cost-effectiveness plane showed that for all simulated cases within the 95% confidence ellipse, there was a QALY improvement between study groups (cases are in both the upper and lower right quadrants). However, slightly more than half the simulated cases within the 95% confidence ellipse were in the upper right quadrant, suggesting that for these cases, the costs were higher in the intervention group compared to the control group. The cost-effectiveness acceptability curve shows that the probability of cost-effectiveness at a willingness-to-pay of $50,000 per QALY is 65%, and at $250K per QALY, the probability is 90% (
