列线图又称诺莫图，是通过多因素回归分析得出各相关因素对结局变量的影响力，构建并用于预测事件风险(如诊断或预测疾病发展与后果等)的统计学预测模型。列线图将复杂的回归方程转变为直观、容易理解的可视化图形，便于评估患者病情与医患沟通。随着医学科技的飞速发展和个性化医疗需求增加，其在临床医学已得到越来越多的关注和广泛应用。本篇短文介绍列线图的基本概念以及在眼科应用的例子。

The alignment diagram, also known as nomogram, is a statistical prediction model used to predict the risk of events(such as diagnosis or prediction of disease development and consequences)by obtaining the influence power of each related factor on outcome variables through multivariate analysis. Nomogram turns the complex regression equation to a visualized diagram that is intuitive and easy to understand. It is convenient to be used for evaluating the patient's condition and communicating with doctors and patients. With rapid advances of medical science and technology and increasing demands of personalized medicine, nomograms has attracted more and more attention and applied extensively in clinical medicine. This short article introduces the basic concepts of nomogram and examples of its application in ophthalmology.
