Figure 2 Scatter plot showing cost effectiveness of cardiac resynchronization therapy with pacemaker-defibrillator (CRT-D) relative to optimal pharmacological therapy (OPT) (10,000 model iterations). The horizontal axis depicts incremental gain in (A) life-years (LYSs) or (B) quality-adjusted life-years (QALYs), whereas the vertical axis depicts incremental cost relative to OPT.
