Cost-Effectiveness Acceptability Curves (CEACs). The probability of islet transplantation being cost-effective decreases with increasing discount rate and rises with WTP threshold levels. The CEACs are for scenarios with different discount rates: 0 % (doted line), 3 % (short-dashed line), 3.5 % (long-dashed line) and 5 % (solid line). The uncertainty spread around the mean cost-effectiveness increases (the curves becoming less steep) with increasing discount rates
