The hypothesis that the relationship between the ANB angle and the Wits appraisal can be expressed by measuring the individual variations in their reference systems and by constructing a model of regression between them and a few parameters describing the reference systems was tested with material consisting of 30 lateral cephalometric radiographs of untreated orthodontic patients with different types of skeletal and/or dentoalveolar malocclusions. The results indicated that approximately 93% of the variation of the Wits appraisal could be explained by the variation of the ANB, NSL/OL, and SNA angles. The study also showed that the results given by different measurements with different reference systems, such as the ANB angle and the Wits appraisal, cannot be directly compared. To obtain comparable interpretations, one should correct the results of both measurements in relation to the variations in their reference systems.
通过测量30张未经治疗的正畸患者的头颅侧位X线片（这些患者患有不同类型的骨骼和/或牙列错颌畸形）组成的材料，对以下假设进行了测试：即通过测量ANB角和Wits评估在其参考系统中的个体差异，并构建它们之间以及描述参考系统的一些参数之间的回归模型，可以表达ANB角与Wits评估之间的关系。结果表明，Wits评估约93%的变异可由ANB、NSL/OL和SNA角的变异来解释。该研究还表明，使用不同参考系统的不同测量方法（如ANB角和Wits评估）给出的结果不能直接比较。为了获得可比的解释，应根据其参考系统的变化对两种测量结果进行校正。
