a Alternative analysis 11: Cost-effectiveness acceptability curve. The graph gives the probability that HL/S (1 %) or EVLT (99 %) would be considered cost effective for a €50000 threshold of willingness to pay. b Monte Carlo simulation of EVLT vs. HL/S. A 10,000-iteration Monte Carlo simulation of a patient undergoing EVLT. The incremental cost and incremental effectiveness of EVLT compared with HL/S is plotted for each iteration. Of 10000.00 iterations, 9879.00 showed EVLT to be cost-effective by possessing ICERs below the €50,000/QALY threshold
