Figure 3. Cost-effectiveness Planes at the 3-Month Follow-up.

Graphs show before treatment to 3-month follow-up cost-effectiveness planes of therapist guided internet-based cognitive behavioral therapy (ICBT) (A) and unguided ICBT (B) compared with face-to-face CBT for obsessive-compulsive disorder. Costs are from a societal perspective and based on the Trimbos and Institute of Medical Technology Assessment Cost Questionnaire on Costs Associated with Psychiatric Illness using Swedish health care tariff listings. The effect is shown as the rate of response, defined as a 35% or more reduction in the Yale-Brown Obsessive Compulsive Scale from before treatment and a Clinical Global Impression–Improvement score of 1 or 2.
