Table 1. Cost-effectiveness results over 20 years ^a .

Intervention	Cost	CAFY	ICER b	NMB c
Course House	€249,000	12.4	€39,000	€641,200
FFT	€222,200	11.7	-	€618,700

CAFY, criminal activity free year; ICER, incremental cost-effectiveness ratio; NMB, net monetary benefit; FFT, Functional Family Therapy.

^a The results represented were averaged over the 10,000 simulations run.

^b The ICER was calculated as the difference in cost divided by the difference in CAFYs between the Course House and FFT.

^c The NMB was calculated by multiplying CAFYs by the WTPvalue of €71,700 per CAFY and subtracting cost. The Course House is cost-effective compared with FFT, because the NMB of the Course House is higher than the NMB of FFT. Due to decimals, the numbers in the table multiplied do not give the exact NMB values represented in this table.
