Appreciation of the multivariate features of data from periodontal research studies is sometimes difficult. This appears to be due to the form of tables and graphs in which information is made available in published studies. A computerized graphical technique, which appears well suited to the multivariable situation, is described. It uses structural analogy between the measurement scales and the variables measured and provides what can be a compelling iconic description of multifaceted data.
理解牙周病研究数据的多元特征有时很困难。这似乎是由于已发表研究中呈现信息的表格和图表形式所致。本文描述了一种似乎非常适合多变量情况的计算机化图形技术。它利用测量尺度与所测量变量之间的结构类比，并提供对多方面数据的极具说服力的标志性描述。
