Figure 2

The bars indicate the range of cost per QALY gained with the CardioMems device compared with usual care in 1-way sensitivity analyses of the input parameters across the range of values, listed to the left and right of the bars. The above variables were selected because they had the largest effect on the cost-effectiveness ratio of the device. The solid line demonstrates the cost-effectiveness in the CHAMPION cohort of $71,462 per QALY gained. The dotted line represents the cost-effectiveness threshold of $150,000 per QALY gained.
