Figure. Cost-effectiveness Planes Using Responder Status as Primary Health Outcome.

Cost-effectiveness planes with responder status as health outcome from the health care professional perspective (A), the health care sector perspective (B), and the societal perspective (C). Each plane has 4 quadrants. Dots in the northwest (NW) quadrant indicate that stepped care is more costly and less effective. Dots in the northeast (NE) quadrant indicate that stepped care is both more costly and more effective. Dots in the southwest (SW) quadrant indicate that stepped care is both less costly and less effective. Dots in the southeast (SE) quadrant indicate that stepped care is less costly and more effective.
