目的：显示心血管疾病（CVD）风险水平和CVD发生率如何用图形表示。研究设计和设置：方法学和使用图形来说明CVD风险预测。使用来自新西兰、中国和苏格兰的三项研究中关于CVD风险和结局的数据，风险水平由多变量菲斯克scores.Results确定：图表清楚地显示风险水平和实际CVD发生率通常不同时发生，许多高风险个体不经历CVD事件，相反，许多CVD事件不发生在标记的高风险中。缩放矩形可以很容易地形成，以显示模型预测的风险水平和CVD的实际发生如何一致。差别待遇很好地说明了这一点。(C)2009 Elsevier Inc.所有的战斗保留。
Objectives: To show how levels of cardiovascular disease (CVD) risk and occurrence of CVD can be graphically represented.Study Design and Setting: Methodological and using graphics to illustrate CVD risk prediction. Uses data on CVD risk and outcomes in three studies from New Zealand, China, and Scotland with levels of risk determined by multivariate fisk scores.Results: The diagrams clearly show that risk levels and actual CVD occurrence do not often occur together, many individuals at high risk do not experience a CVD event and conversely, many CVD events do not occur in the labeled high risk.Conclusion: Scaled rectangles can easily be formed to show how modeled predicted risk levels and actual occurrence of CVD coincide. Poor discrimination is well illustrated. (C) 2009 Elsevier Inc. All fights reserved.
