Figure 7:

Abbreviations: CBT, cognitive behavioural therapy; iCBT, internet-delivered CBT; QALY, quality-adjusted life-year; WTP, willingness to pay. The cost-effectiveness acceptability curve graphically presents the probability of cost-effectiveness of the examined CBT strategies and usual care across various willingness to pay values on the x–y coordinate system. The x-axis shows the probability of cost-effectiveness (range: 0–1) and the y-axis represents willingness to pay values (range: $0 to $100,000 per QALY gained).
