Figure 4 Tornado diagram of variables with significant influence on incremental cost-effectiveness for the moderate stroke-risk cohorts. Variables identified in one-way sensitivity analysis with the largest impact on incremental cost-effectiveness are depicted. The analysis compares left atrial catheter ablation (LACA) with rate control therapy for 65-year-old (solid bars) and 55-year-old (ruled bars) moderate stroke-risk cohorts. AF = atrial fibrillation; QALY = quality-adjusted life-year.
