Abstract

The CT scans of 18 chronic schizophrenic patients and 17 controls were evaluated for Ventricular Brain Ratio (VBR) size. A trend for the patient group to have larger VBR than controls was present but did not reach statistical significance at the 5% level. Age was found to be an important correlate of VBR within the patient group but not among controls. In a stepwise multiple-regression model age, among other independent variables, can account for 47% of VBR variance in schizophrenic patients. Linear regression analysis did not reveal significant association between VBR and age in control subjects.

摘要

对18名慢性精神分裂症患者和17名对照者的CT扫描进行了脑室脑比率（VBR）大小评估。患者组的VBR有大于对照组的趋势，但在5%水平未达到统计学显著性。发现年龄是患者组中VBR的一个重要相关因素，但在对照组中并非如此。在逐步多元回归模型中，年龄以及其他自变量可解释精神分裂症患者VBR变异的47%。线性回归分析未显示对照组中VBR与年龄之间存在显著关联。
