Fig. 4From: Cost-utility of two minimally-invasive surgical techniques for operable oropharyngeal cancer: transoral robotic surgery versus transoral laser microsurgery1 way sensitivity analysis on cost of TLM (based on number of re-resections needed for negative margins), cost of TORS, and 2-way sensitivity analysis combining the two. NMB = WTP*QALMs. NOTE: Higher expected value in one-way analyses corresponds to the winning strategy. Similarly, the color of the area containing a specific point in the 2-way analysis plane identifies the winning strategy (i.e. dominating or with a higher utility and an ICUR < threshold)Back to article page
