Table 4.

Estimated mean differences in healthcare cost between ICBT and CBGT for different assumptions of practical capacity

Assumed practical capacity of full theoretical capacity	Mean cost difference (€)	95% CI of the difference
		Lower	Upper
50%	481	374	587
80%	343	267	420
100%	299	232	365

Independent-samples t-tests were conducted to compare total costs for ICBT and CBGT for different levels of assumed practical capacity in relation to theoretical full capacity, indicating significant differences in healthcare costs; t(124)=8.9, p<0.001.
