 One way sensitivity analysis of cost of ablative therapy versus average cost effectiveness. As the cost of ablative therapy declines, it becomes the strategy yielding the best average cost effectiveness. When total costs (including drug costs, procedure costs, and follow up endoscopic examinations in the immediate post ablation period) are less than $15 000, the average cost effectiveness of ablation is superior to all other active strategies.
