Cost-effectiveness plane — Telehealth CBT for adult anxiety — base caseCost-effectiveness plane of 4 strategies against Standard of care (clinic GAD-7 + meds). Guided self-help app + coach: USD 1,900, 3.66 QALYs, on the frontier. Standard of care (clinic GAD-7 + meds): USD 4,200, 3.41 QALYs, reference. Telehealth CBT (12 sessions): USD 5,400, 3.78 QALYs, on the frontier, ICER USD 29,167 per QALY against Guided self-help app + coach.

Each ICER is sequential — against the strategy directly below it on the frontier, not against Standard of care (clinic GAD-7 + meds). Fullincremental analysis: strategies ordered by cost, strongly dominated options (×) removed, then extendedly dominated options (◇) removed until the ratios rise.
