Cost-effectiveness plane of locomotor strategies (conventional and overground robotic) in people with incomplete spinal cord injury (A) and complete spinal cord injury (B). The cost-effectiveness plane shows four quadrants where an intervention can fall relative baseline. Estimates that fall in the upper right quadrant show strategies that are more effective and cost more, lower right quadrant shows strategies that are more effective and cost less (cost saving), lower left quadrant show strategies that are less effective and costs less, and upper left quadrant show strategies that are less effective and costs more (dominated)
