Cost-Effectiveness Plane

Each point represents the result of 1 of the 1,000 simulations. Points to the left of the vertical axis are simulation results in which quadripolar CRTD was more effective and less expensive than bipolar CRTD. Points to the right of the vertical axis are simulation results in which quadripolar CRTD was more effective and more expensive than bipolar CRTD. The diagonal black line is the £20,000 ($30,000) per QALY gained line (i.e., all points above this are simulation results in which the incremental cost per QALY gained was <£20,000 [$30,000]). Abbreviations as in Figure 2.
