Assuming a practical work capacity for personnel varying between 100%, 80% and 50% of theoretical full capacity, the cost for ICBT varied in the range between 400\u20ac, 463\u20ac and 654 \u20ac, while the cost for CBGT varied between 699\u20ac, 806\u20ac and 1134\u20ac. Within-group effect size was \u22120.36 (95% CI \u22120.70 to \u22120.01) for ICBT and \u22120.25 (95% CI \u22120.60 to 0.10) for CBGT.
