Results of Base-Case Analyses. The table depicts a visual heuristic to help identify the optimal strategy by patient age, cyst size, and patient preference for unadjusted vs. quality adjusted survival. Shading demonstrates the degree of superiority over the competing strategies. Each number represents the length of discounted years that a patient will live, on average, with each individual strategy. For instance, if an 85 year old patient has a 3cm cyst, then a pancreaticoduodenectomy (Whipple) adds a modest 0.356 years over the other strategies. However, if quality of life is desired over unadjusted survival, then the invasive surveillance strategy is superior, although it provides a minimal benefit of 0.030 years of quality adjusted life compared to the next closest competitor.
