By using the quantification method for multidimensional qualitative data, 13 variables were analyzed. The younger the patient, the stronger was the correlation between age and positive glycerin and urea tests. At ages over 50 years no correlation with positive test results was found. The longer the duration of disease, the stronger was the correlation between this duration and a positive urea test. The glycerin test showed no correlation with the duration of the disease. Hearing losses of 40 to 69 dB. were correlated with both a positive glycerin test and a positive urea test. Greater hearing losses were correlated only to a positive glycerin test. Hearing losses less than 39 dB. were not correlated with positive results in either the glycerin or the urea test.
采用多维定性数据的量化方法，对13个变量进行了分析。患者年龄越小，年龄与甘油试验及尿素试验阳性之间的相关性越强。50岁以上患者未发现与试验阳性结果存在相关性。病程越长，病程与尿素试验阳性之间的相关性越强。甘油试验与病程无相关性。听力损失40至69分贝与甘油试验阳性及尿素试验阳性均相关。听力损失越大仅与甘油试验阳性相关。听力损失小于39分贝与甘油试验或尿素试验阳性结果均无相关性。
