The concept of cost-effectiveness is illustrated graphically on the CE plane. Strategies are represented according to their effectiveness (e) and cost (c) relative to those of some reference standard. A straight line with slope K passes through the origin, where K is the maximum acceptable cost-effectiveness ratio. Strategies plotted to the right of line K are cost-effective, while those plotted to the left are not. Furthermore, the most cost-effective of two or more mutually exclusive alternatives is that plotted the greatest distance to the right of K. The CE plane can be used to resolve ambiguities about the meaning of cost-effectiveness and to illustrate its relevance to medical decision making.
成本效益的概念在成本效益（CE）平面上以图形方式说明。策略根据其相对于某些参考标准的有效性（e）和成本（c）来表示。一条斜率为K的直线经过原点，其中K是最大可接受成本效益比。绘制在直线K右侧的策略具有成本效益，而绘制在左侧的则没有。此外，两个或多个相互排斥的替代方案中最具成本效益的是绘制在K右侧距离最远的那个。CE平面可用于解决关于成本效益含义的模糊性，并说明其与医疗决策的相关性。
